Removing paint/sealant from fiberglass/gelcoat

[smiybrneyes]

I recently purchased a 1992 Tioga. The previous owner had for some reason painted a portion at the very top of the cabover with either white paint or just carried over from the roof the white sealant he used on the roof about 1/3 of the way down the cabover (I'm guessing the white roof sealant that he had painted all over the roof). What is the best way to remove this paint/sealant? Is it okay to use acetone or will that damage the fiberglass? I researched on the internet and some boat owners say use oven cleaner. Please help. Thanks!

i used acetone to remove all the old sealant mess that was smeared over a repair. the filon (fiberglass sheet) ended up perfectly clean, but there is a light brown stain left behind. still need to get that off now that i have resealed the area neatly.

You might try some Goof Off, follow directions. Available at harware stores.
This stuff works very well on all the hard surfaces I have used it on so far. A little elbow greese and a some soak time helps.
