No, and most of the suggestions in here are for products that people have tried with good results....but for slightly different purposes than your current need.
What I have found...
from experience...and it is simply logical, is that when you find a specialty business operating in its own niche, and it matches your problem, they usually have a lot of acquired experience AND expertise which they are happy to share with their customers to help them find a solution.
If it were my boat top that was stained I would call them just to see what they could offer; doesn't cost anything.
I was not shilling for any product, just offering another option. Sorry for wasting your time.
