Re: Gelcoat Mildew-I'm so sick of gelcoat mildew
I suffer thru something similar. I have barn swallows that use my boat for a habitat when I'm not around which not only stains my deck but helps fertilize the mold. My solution has been to use Soft Scrub with bleach and then apply woody wax. Soft scrub is for fiberglass showers why not boats? It sparkles after that. Much easier to keep clean. I've been using "Nu-finish" on my hull which has been amazing for a fraction of the price. Scrub,buff and apply two coats. "The once a year car wax"; it's recommended for boats. Hopefully it doesn't ruin my gel-coat for future painting down the road.
I'm going to try a little on the deck this year. I'm concerned that it may make the deck to slippery.
