Things You'll Need
Instructions
Place the model in your polythene bucket. The bucket must be polythene as caustic soda will eat through tin and other weak metals.
Pour enough water into the bucket to fully cover the model. The water should be at least 1 inch above the top of the toy.
Add caustic soda to the water. You must wear gloves as caustic soda can burn the skin. The model should remain in the solution for approximately three minutes.
Use your brush to remove the model and inspect for paint. The caustic soda should quickly dissolve the paint and you can brush away any remaining flakes. This may take longer for larger models.
Rinse the model and brush with cold running water once all paint has been removed. Make sure that all of the soda water is gone and the model is fully dry before you begin painting.
Prime and re-paint the dried model. Metallic primer is best as it will accentuate unpainted areas. A size 5 paint brush is recommended due to the level of detail it makes possible while still covering large areas.
