Silicone caulk problem

I would like to refinish my Scamp, paint or gelcoat. My problem is that someone smeared silicone around every bolt and rivit on it. Anybody suggest a solution.

Take a very sharp raiser blade and very carefully try to remove it.

I believe that there is a chemical remover for silicone. Might be in a spray can.

Hi patsublett, I had the same problem around my windows. A razor may scratch you finish but be helpful in lifting off big glops of silicone. Mineral spirits on a cloth worked the best for me. Try applying on a few rivits on the roof where it won't be noticed and see how it goes. It worked fine for me, but each case maybe different

Yes a razor blade will scratch the gel-coat if you are not careful, but it can work to safely get off the majority of the silly cone caulk off, but only if you are careful. Then, various solvents will soften the silicone, mineral spirits and pro-strength "Goof-Off" being two good choices. Soaking a rag with them and leaving them on the caulk for a few minutes is sometimes suggested. Then use soft tools such as plastic knives to scrape away the rest (without gouging the finish). It will take some time and effort. Last, I would use acetone on the gel-coat (but nowhere else).

It is mostly mechanical removal of the caulk (elbow grease) along with softening the most stubborn bit that never seems to want to come off.

Go to the paint department of your local hardware store. They should have plastic razor blades. They look just like an old fashioned single edge blade. They usually come with a handle and are used for scraping.

Wear rubber gloves using solvent, or you could end up like me.
