Chemical to remove adhesive caulk?

Is there any chemical that will remove adhesive caulk? Just took the trolling motor bracket off the boat and there's a bunch of adhesive caulk residue left on the fiberglass. Don't wanna try and scrape it off and scratch the fiberglass up.

Gasoline, acetone, brake cleaner, carb cleaner

I'd start by trying:

I've used this to remove silicone around a sink. Not sure if it will effect the fiberglass.

If you scratch it just use some wet sandpaper and get the scratch out. Then buff.
Gelcoat is pretty tough.

If it was silicon caulk, and you plan on doing any kind of touch up paint work, you are going to have to sand off. You can scrub off the visible residue with whatever kind of googone type shite you have laying around but you will never be able to paint or bond anything to the area unless it's sanded off completely.
Hopefully it was something other than silicon. Silicon caulk has no business in a boat.

If it's 3M 5200, they make a release formula.
Also, a regular razor blade has one sharp side and one flat side. You can slide one of the sides under the caulk without scratching or digging into your gelcoat. I forget which side though, lol.
Edit: I think it's the sharp side facing up and you hold the blade at an angle where the sharp side barely touches the gelcoat. In the other direction (sharp side down), it will dig into the gelcoat like a shovel.*
*its been a long time since I've done high end yacht refinishing work.

DeBond.
Acetone will also work but it evaporates quickly. Methyl Ethyl Ketone works too.

it's actually called antibond
it works but it's messy
I've always found mechanical removal is easier and quicker
a razor blade and a steady hand
