Something that I have been able to use on car, boat, canoe, anything is
Rapid Tap. I'm not sure where you can get it from but it's used for tapping
threads in pipe and steel. It works and doesn't damage the paint, gelcoat
or materials.... plus it's cheap.

Good Luck!

Spent a nice day on a coworkers 26' Macgreger Sailboat.
Beautiful boat except it recently was stored under a tree
and has horrible sap stains all over it.
He says he has tried everything. Today I tried Xtreme hull cleaner, a
product I found worked really well on waterline scum ,basically an acid,
it
didnt work at all.
Any suggestions? Magic potions? Grammas old recipies?
Thanks in advance.
