Cleaning yellowed and discolored gelcoat


A discolored gelcoat can never be polished to a good result, it needs to be bleached/faded back to its original color.

Use our Gelcoat Cleaner, an acid-based gel that whitens the gelcoat. Wash the surface with Boat Cleaner, rinse with water, apply Gelcoat Cleaner – let sit for 3-5 minutes – rinse with water. If the surface is heavily discolored, repeat the treatment.
