Dried Sap on Gelcoat

[Ted R]

Any ideas on how I can remove dried tree sap from gelcoat?

Try some mineral spirits.

I tried mineral spirits was not very effective, any other suggestions?

Laquer thinner. Go easy. Re wax when done.

Lacquer thinner may work but it does remove the wax as mentioned. Acetone will probably work too. Sometimes it is helps to wet/soak the sap with warm water, let it sit, re-soak and them scrub. You can also try sap remover available at automotive stores.
Prior to using sap remover, dry the area the area. After the removal, soap and rinse, apply some wax.

Goof Off.

It's a mixture of toluene and xylene that is available just about everywhere. I've used it to remove pine sap from my gelcoat many times. You just have to wash and re-wax or polish the treated area.

Turpentine. It's not instant process, but you'll get there. Wax when done ... :|

Try denatured alcohol, used it on my car (and boat) under pine trees. Disolves the sap very fast.

Acetone will probably work too.

Indeed acetone should handle it quickly.

Thanks for all the suggestions, nothing worked until a gentleman at the marina that was working on his Bertram mentioned to me to try "Buff Magic" from Shurhold, he had some and let me use it, the dried stuff came off easily, this product is very well named, it was magic. Everybody should have a can of it for all purpose gelcoat cleaner.
