Typically, gelcoat is not recommended over TotalBoat Thixo Flex Thickened Flexible Epoxy Adhesive because the two products are chemically incompatible, and the gelcoat will not adhere properly.

However, for relatively small cosmetic repairs, Thixo Flex can be used in the repair layup if you follow these steps:

• Measure the epoxy and hardener accurately, mix properly, and apply as directed.
• Allow it to cure completely.
• Use an abrasive pad and water, not solvent, to remove any amine blush completely, then allow the repair to dry fully.
• Prepare the surface according to the gelcoat manufacturer’s directions.
• After sanding and fairing, clean the surface thoroughly with acetone.
• Apply the gelcoat finish beyond the edges of the repair area.
