How to remove varnish & sealant from non-skid?

I am trying to remove varnish and old sealant that is on the non-skid gelcoat. What is the strongest cleaner that will not do damage to the gelcoat?

Try citrus gel or soy gel or lacquer thinner ( none will hurt the gelcoat )and a scrub brush

1955 Blanchard 51 Custom ( I got a woody )

1974 Ranger 33

Lord, give me coffee to change the things I can change and Rum to accept the things I can't

Any paint stripper will handle the varnish, and won't damage the gelcoat. I'd just make very sure that it IS gelcoat before I starting slopping stripper around.

The sealant's gonna be a lttle different. I'd first try to carefully remove it with a razor blade scrapper. Depending on what type of sealant you're dealing with, you may need to resort to chemical warfare. I've had luck getting polysulfides off with acetone and PB Blaster. 3M General Purpose Adhesive Remover may also work. If it's 3M 5200, you'll probably need to resort to DeBond 2000.
