Anyone Know anything about Fibreglass.?

I have a front spoiler that doenst fit right, and was wondering if there was any way to temporarily soften the fiberglass, bend it to fit better and let it re harden.

Is this possible?

Nope not really, depedning on how bad it is what you can do is take a diamond saw blade in the angle grinder (a tile cutting one will work if you are cheap) slice through it in parallel strips where the shape is wrong, then re-fibreglass it to hold shape. After fibreglassing one of the nicest ways of filling is it polyester resin (Fibreglass resin) and some talk powder, very nice to sand etc.

PS If its not too badly bent it may just hold shape well once attached to the car ie if its only a couple of cm's?
