Using Specialized Solvents
For stubborn decals, using a specialized decal removal solvent is an effective option. Apply a small amount of the solvent to the edges of the decal using a cotton swab. Allow the solvent to soak into the adhesive for a few minutes, softening the bond between the decal and the model. Carefully use a hobby knife or a plastic scraper to lift the edges and peel off the decal. Make sure to test the solvent on a hidden area first to ensure it doesn’t damage the paint. Wipe away any excess solvent and decal residue immediately after removal. Using solvents is a very effective option for older and more damaged decals.
Scraping Decals Off
When the decals are softened, the next step is to carefully scrape them off the surface. Use a hobby knife or a plastic scraper with a blunt edge to gently lift the edges of the decal. Avoid applying too much force, as this can damage the paint. If the decal is particularly stubborn, apply more heat or solvent and allow it to soak for a longer period. Work slowly and methodically, removing small sections of the decal at a time. Use tweezers to remove the small pieces of the decal. It is important to exercise patience and care during this step to prevent any damage.
Cleaning and Preparing the Model
After removing the decals, the model’s surface needs to be thoroughly cleaned to remove any remaining adhesive residue. Cleaning the model helps to ensure that any new decals will adhere properly and that the surface is ready for any further customization or restoration work. The quality of this step directly affects the final result and helps to preserve the model’s finish. This step will prepare the model for its next step, whether that’s repainting or further detailing.
Removing Adhesive Residue
Use a soft cloth or cotton swab to apply isopropyl alcohol or a specialized adhesive remover to the area where the decals were. Gently rub the area to dissolve the adhesive. Be careful not to apply too much pressure, as this could damage the paint. If the adhesive is stubborn, you can let the solvent sit for a few minutes before wiping it off. Repeat the process until all the adhesive is removed. Inspect the surface carefully to ensure that no residue remains. This step is essential to guarantee a smooth surface for any future decals or repainting, and ensuring that there are no sticky areas on the model.
Polishing and Protecting the Finish
Once the adhesive residue is removed, it’s important to polish the surface to restore its shine. Use a polishing compound suitable for the model’s paint type and gently rub it onto the surface with a soft cloth. This will remove any minor imperfections and restore the original shine. After polishing, you can apply a protective wax or sealant to protect the paint finish from scratches and other damage. This will help to preserve the model’s appearance and value.
