Flush with fresh water to remove the soap residue and allow to dry. Remove mold release wax using one of the following methods. The preferred method of cleaning gelcoat is to apply Fiberglass Surface Prep YMA601 with a maroon, 3M Scotch-Brite pad and scrub well. Flush with fresh water or wipe off with a clean, wet cloth ensuring that no traces of Fiberglass Surface Prep remain. An alternate method would be to dampen cheesecloth with Fiberglass Solvent Wash 202. Wipe thoroughly to remove all surface contamination and cleaners. Wipe off with a clean, dry rag before liquid dries. Wipe only a few square feet at a time and change rags frequently. To be certain the contamination has been removed, run water over the surface. If the water beads up or separates, repeat one of the above methods. When the water sheets off, all contamination has be removed. Sanding does not remove contamination.
