BARE FIBERGLASS: Begin by scrubbing well using soap and water and a stiff brush. Rinse with fresh water and allow to dry. Wipe a small area with a clean rag that has been wetted with Fiberglass Solvent Wash 202. While the surface is still wet, wipe with a clean, dry rag. Continue this process until the entire surface has been cleaned. Sand with 80 grade (grit) paper. Remove sanding residue. Wipe with Fiberglass Solvent Wash 202. Alternative degreasing methods include the use of 202V Low VOC degreaser or YMA601 Fiberglass Surface Prep. For complete details see the Interprotect Bulletin - The Ultimate No Sand System. Once the hull is contaminent-free and dry, apply the first coat of primer.

BARE WOOD: Sand with 80 grade (grit) paper. Remove sanding residue. Apply first coat reduced 10% with Special Thinner 216. If primer is preferred use Primocon YPA984. Fill seams, if necessary, with Seam Compound Brown 30.
