Since you have already tried bleach I would consider painting it. The mildew has grown into and stained the relatively porous gelcoat. The only other idea I have is to try SoftScrub with bleach before painting. Let the SoftScrub sit there for a while and try it multiple times.

I am saving that for a last option hopeing beyond hope for an easier answer.Thanks Dave

Micro ban it's what is used by commercial cleaners. Also it's a pretreatment in a lot of carets

If it's gelcoat try a sloppy acetone rag, or if it's smooth (as in not textured) try a buffer or even wetsand it.
