Okay well my girlfriend drove my car to work the other day and my sunroof has been acting up, sometimes it doesn't want to close all the way. well i guess she didnt check to make sure it was sealed and sure as shit, it POURED! so my headliner got soaked and is now drooping down in spots. plus it's got cigarette burn holes from me so i planned on replacing it with a black one. Question is how hard would it be to fiberglass it? I searched but never got a clear answer on exactly how to do it. I've never done glassing but it's something I've been dying to try my hand at. If I'm lucky mike will chime in here and shed some of his knowledge. ;) any info is appreciated.
