Thanks for the reply! Yes, Iíve actually already come across that thread already and have googled quite a bit.
Some said that Acetone will destroy the gelcoat which I donít care about, but it does make me question what it will do to the fibers underneath, and I have yet to find a solution for this specific situation.
The heat gun I used previously did a fair amount of work on the larger pieces when combined with elbow grease, but Iím unsure of how interwoven the fibers and silicone are.
I suppose Iíll keep hunting.
