How to Remove Excess Paint from Plastic Model Kits

Dealing with excess paint or paint mishaps is a common challenge for many modelers. Fortunately, there are several effective techniques to remove excess paint without damaging your model.

1. Understand the Paint Types

Before you start, it’s crucial to know what type of paint you used. Common model paints include acrylics, enamels, and lacquers, each requiring different removal techniques.

2. Prepare Your Work Area

Ensure you work in a well-ventilated area, preferably with a dedicated workspace for model building. Gather the necessary tools and materials:

Cotton swabs or brushes

Plastic or metal scrapers

Tamiya Airbrush Cleaner, Rubbing alcohol (for acrylics)

Mineral spirits or Enamel thinner (for enamels)

Acetone, nail polish remover, Lacquer thinner (for lacquers)

Mild soap and water

Soft cloth or paper towels

Cotton Swabs — Prepping your workstation.

3. Remove Excess Paint

Acrylic Paint

Dampen a Cotton Swab: Moisten a cotton swab with rubbing alcohol. Gently dab the excess paint to soften it.

Wipe Away: Use a clean cloth or paper towel to gently wipe away the softened paint. Be careful not to damage the plastic or affect any adjacent painted areas.

Clean the Area: Wash the model part with mild soap and water to remove any residue from the rubbing alcohol.

Enamel Paint

Apply Thinner: Dampen a cotton swab or brush with mineral spirits or enamel thinner. Gently apply it to the excess paint.

Scrape Gently: Once the paint starts to soften, use a plastic or metal scraper to carefully lift it away. Avoid using excessive force to prevent damaging the model.

Clean Up: Wash the affected area with mild soap and water to remove any remaining thinner.

Lacquer Paint

Lacquer Thinner: Apply a small amount of acetone, nail polish remover or lacquer thinner to a cotton swab. Test it on an inconspicuous area first to ensure it doesn’t damage the plastic.

Remove Excess Paint: Gently rub the excess paint with the cotton swab. Lacquer paints can be aggressive, so work slowly and cautiously.

Rinse and Clean: Rinse the model with water to remove any acetone residue and then wash with mild soap and water.

4. Preventive Measures

Use a Primer: Applying a primer before painting helps the paint adhere better and reduces the risk of paint bleeding or pooling.

Thin Your Paint: Properly thinning your paint can help prevent excess build-up and achieve a smoother application.

Work in Thin Layers: Applying paint in thin layers helps manage paint application and reduces the likelihood of needing to remove excess.

5. Final Touches

After removing excess paint, inspect the model for any damage or irregularities. Touch up any areas that may need it, and allow the model to dry thoroughly before handling or continuing with additional painting.

6. Practice and Patience

Removing excess paint can be a delicate process. It may take some practice to perfect your technique, so don’t be discouraged by initial challenges. Patience and careful handling are key to achieving the best results.
