Ferrari Monza SP2 1/24 Scale Model Build Guide (AlphaModel)
I. Unboxing
After opening the product package, take out all the parts bags and the car body. Since the product may be damaged during transportation through the logistics company, you must first check whether the parts are defective. The A-pillar of the car shell is more easily damaged. , brake calipers, wheel rims and other small parts. After confirming that the parts are not damaged, please check whether the etched sheet is bent and damaged and whether the water sticker is stained. After confirming that all standard items are normal, you can start the preparation work for production.
AlphaModel provides a wealth of carbon fiber decals on a large number of parts, including the steering wheel, shift paddles, center console, instrument panel, rear diffuser, air knife, etc., which are basically the same as the real car. In addition, the main and passenger seats in the cab Details such as floor mats and seat belts are also enhanced with etched sheets, and a variety of decals are provided according to different vehicle colors. I believe the effect will be amazing after the production is completed.
AlphaModel's products have precise mold opening, especially in the production technology of car casings. The car casings have precise shapes, smooth surfaces without burrs and shrinkage, deep engraved lines, and sharp edges. These features greatly reduce the difficulty of production and are very suitable for Newbie.
This product not only has traditional brake discs, interior details and other details, but also has a complete engine for players to make. There are a large number of detailed pictures of real cars on the Internet for your reference. After the production is completed, you can see the engine at the rear of the car. Cover window gives full view of the engine.
Each car has its own unique color matching, and players can also color it according to their own preferences. Before production, you can refer to photos of the actual car and mark the color of each part on the product manual to facilitate later coloring; in Ferrari In the process of making the Monza SP2 car, we need to prepare some necessary tools in advance, such as: outline pen, paper sandpaper, sponge sandpaper, instant glue, tweezers, marking knife, pen knife, etching sheet bending pliers Etc., there are tools that are handy and feel good when making, which can help players create high-quality static models more easily.
Use dish soap or other resin cleaning fluid to clean all the resin parts. Because there is a layer of grease release agent on the surface of the workpiece, if it is not clear and directly sprayed, problems such as fish eyes and lack of adhesion of the paint will cause discoloration. After cleaning, Just let it dry.




II. Car body treatment
First, observe various parts of the 1/24 Scale car shell. Generally, there will be some unevenness at the bottom of the side skirts. You can first use sandpaper to polish and level it. After making sure there are no problems such as missing flesh, use a 0.15mm caliber scoring knife to deepen the scoring. Although the car The engraved lines on the shell itself are relatively clear, but we need to manually deepen them again. This is to make it more three-dimensional after the production is completed. We can also consider not bleeding the lines and using natural shadows to show the texture of the engraved lines.
When carving, you need to pay attention to the intensity from light to heavy. First, gently draw 2 knife along the carving line, and then slowly apply pressure; at the arc position, you can use the elbow hook knife to deepen the carving line. If there is no hook, Line knife, when using a straight-edged scoring knife to deepen, do not carve out of bounds to avoid more trouble, and pay attention to the angle of the knife head, do not carve the curved score line into a straight line.
After adding the deep lines, first use No. 800 paper sandpaper to polish and level the entire car shell. This will increase the sharpness of the entire car. The position of the engraved lines will be more obvious and the position of the large plane will be smoother. In the later stage of painting, The effect will be better with varnish. During the polishing process, be careful to use light force on the arcs and protruding parts to avoid grinding away the complex details. After leveling, use 1000 and 1500 grit sandpaper to remove the thicker parts. Sand off the scratches, and then use 1500 and 2000 sponge sandpaper to polish it again. Use high-grit sandpaper to apply a little more force, which will make it easier to polish off the rough scratches. Only after the surface of the workpiece has been properly treated, The effect will be better.
Be careful to wear a gas mask during the polishing process. Resin dust is toxic, so pay attention to protection.

III. Preassembly
Use nozzle pliers to cut off the nozzle of the part bit by bit. Do not cut off the entire nozzle at once to avoid missing flesh. Assemble the polished parts according to the part number in the instruction manual. Alphamodel's mold opening is very precise, and every part They can all be assembled directly, with perfect fit and reasonable spout position. In addition, the plain assembly can also let players know the order of some parts during the assembly process, so that they will not install the wrong parts during the final assembly.
In the process of polishing the nozzle and the element assembly, be careful not to use excessive force to cause damage to some very small parts. The parts are easy to fall apart when clamped with tweezers. Parts that are not easy to clamp can be assembled with a dispensing pen. The adhesive used in the plain group can use blue butyl glue.
Referring to the actual car drawings, you can determine the color of each component, and choose the appropriate paint for spraying based on different colors and glosses. If you want to paste water stickers on the instrument panel, center console, and door interior panels, you need to use semi-gloss. Use black (Gunshi C92) as the base, which can effectively avoid color leakage.
For
Ferrari Monza SP2 metal parts such as etched sheets, after using 800-grit sandpaper to remove the thick oxide layer on the surface, you can use Gunshi SF287 No. 1000 water-replenishing soil for primer. This water-replenishing soil can provide strong attachment to the metal surface. Be careful not to cause the paint to fall off with the slightest touch after it dries.
IV. Coloring
I chose plate spraying for the etched film. First, I used masking tape to cover the parts that did not need to be painted, and then used 800-grit sandpaper to polish the parts that needed to be painted. Before painting, I used Gunshi SF287 water to make the base. When spraying, be careful not to spray too thin. Use an airbrush to sweep and spray in multiple layers, allowing the paint particles to adhere to the surface of the part layer by layer. Wait for it to dry before spraying the topcoat. I used Gunshi for the brake disc retainer. C28 (black iron color), I used Gunji C33 (matt black) for the cab floor mats, and C92 (semi-gloss black) for other parts. Some parts such as the shift paddles need to be affixed with carbon fiber stickers, so they must be Use black as the base. As for the gloss, you don’t need to choose, because after applying the decals, you need to spray a layer of clear paint to unify the gloss.
After the resin parts are colored, you can stick the etching sheet on them. Use a toothpick to apply instant cyanoacrylate on the parts. Use tweezers and a glue dispensing pen to operate. The toothpick dispensing glue can prevent excessive glue spots from causing glue overflow. The glue can Choose jelly or liquid glue. Liquid glue dries quickly, but due to its high fluidity, glue may overflow when bonding small parts. Jelly glue dries slowly, but has poor fluidity, which will cause etching. After the pieces are attached, you can adjust the shape in a short time. After reaching your satisfaction, wait for more than ten seconds to dry. For some very small parts, you can use Microscale MI-9 and MI-10 to paste them. The glue can reach the strength of fixing the parts. Once you encounter the problem of glue overflow, you can use a cotton swab dipped in water to wipe off the excess glue without leaving any trace.
You can use Microscale MI-1 and MI-2 to assist in the bonding process of carbon fiber water stickers. MI-1 is a backing glue to increase the stickiness of the water sticker, and MI-2 is a softener. After brushing the softener on complex curved surfaces, you can Increase the ductility of the water sticker to better fit the parts.
Ⅴ. Internal components
The air-conditioning outlets can be sprayed in semi-gloss black (Gunshi C92) to form a natural contrast with the carbon fiber of the instrument panel, which can improve the look and feel.
The glove box is made of matte black (Gunshi C33). The buckle etched piece of the glove box strap is very small. When dispensing glue, be careful not to dispense too much to prevent glue from overflowing.
The LED indicator light on the top of the steering wheel needs to be attached with the etching sheet first and then the water sticker. Since the parts are small, be careful not to overflow when dispensing and pasting them. You can use jelly glue to bond them.
The airbag cover is made of semi-gloss black, and when attaching the Prancing Horse logo, pay attention to adjusting the angle of the sticker.
Before spraying, you can assemble it with the car shell to determine the position of the spray color to avoid omission and rework.
Be gentle when applying carbon fiber stickers to the rearview mirror to avoid damaging the parts with excessive force.
The interior of the door panel is made of full carbon fiber water sticker. Because the surface of the part is composed of complex planes, a softener is used to soften it and then slowly shape it, and finally it is fixed with a heat gun.
The carbon fiber water sticker on the back of the seat needs to be pasted carefully. If you feel that the irregularity of the curved surface makes it difficult to paste, you can cut it in advance and then splice each piece together.
After the carbon fiber decals were applied to the diffuser, I sprayed a layer of silicone-based varnish on the surface according to the gloss of the real car. This varnish is thinner than amino varnish, and it can also achieve a mirror effect after it is completely dry, but The disadvantage is that it cannot be polished or repainted, so it requires higher spraying techniques.
I chose to use Finisher’s chrome silver for the exhaust tail package and tail throat. After being fully sprayed, it is not glossy but maintains texture.
The tail bag protective net is sprayed in semi-gloss black (Gunshi C92), which can contrast with the gloss of the diffuser and improve the look and feel.
The rim is primed with bright black, and then sprayed with tungsten steel color. During the spraying process, multiple layers of thin spraying are required. Pay attention to the changes in color to avoid color difference.
When fixing the rear windshield, pay attention to avoid glue spillage. You can put a little glue around the opening, and then use a third-party rivet-etched patch to stick it on it to cover the blemishes.
The surfaces of parts with carbon fiber patterns such as the front shovel, dashboard cover, and side skirts are also sprayed with silicone-based varnish to achieve a mirror effect.
