I am posting this for a friend of mine.
I “painted” my old Champion boat using a roll on bed liner. Actually came looking pretty good. Red red red! One pic shows area I masked of and left the old fiberglass as I wasn’t sure the new numbers would stick to the paint. Covered that area with vinyl wrap made for cars, then stuck the numbers to the vinyl. Splash well looks clean, shows the paint texture. Now step pad also shows the texture. Close up of the unpainted area for the numbers shows the chalky fiberglass and cracks that were all over the top cap. Then a couple pics of the completed boat.
