Recently picked up a 1992 century antigua 235 basically when i got it it was sitting outside un covered for years moss and mold all over. Power washed and bleached it now its white as a ghost and looks good but i am trying to get it to shine up a bit its dull. I have tried a few cleaner/polishes/waxes but it seams like i wipe it on it looks good it drys i wipe it off and it goes back dull like its not sticking to the fiberglass or something.. never had a boat this bad Any suggestions? would using like a compound help?
