Fibreglassing Round Edges.

[AUS R32]

Hey im after some info on how to custom make fibreglass so that its fits my car.

Ill explain what my problem is,

I have an r32 and where the back seats are there is the covering around the window part there, seeing that its a 1992 its been in sun and that its fragile and sadly got mine with a broken trim. All the plastic in the top right of it (this is on my LHS) near the headrest of the passenger seat is all broken. so i was just wondering if theres a way do fibreglass round edges, i havent fibreglassed before but ill try till i get it right.

Any info on what to use etc would be great. Thanks jim.

For a job like that, you'llbe better using fibreglass sheets and resin, rather than the stuff you mix into a paste. That way you can lay it down to follow the curves.

Can you put up a pic of what part you want to fix to give a better idea of what you're trynig to do?

If it is just really a cosmetic fix you're after you could just cover it in material, stretch old T-shirt etc and coat that in resin to make it hard. Sand back the peaks on it and then put a thin layer of bog on it and paint what ever colour you mant to. If youneed a bit more strength glass some light FG matting on before bogging. You're best to sand the plastic beforehand to roughen up the surface. Fiberglass doesn't really stick to plastics so it helps to make a little bit of a mechanical bond. If you want to make an even better mechanical bond b/w the fiberglass and plastic item you can also drill a few small holes in it and then loosly put some tape over the back of the holes. When you fiberglass on the front side it seeps through the holes and flows into the cavity left by the loose tape. This puts a 'flat' top on the end of it and it can't pull through so it holds it to the plastic.

If the plastic part needs to flex don't put anything on that's too thick otherwise it may not flex.

try fiberglassing the whole trim, make a copy and use that, fiberglass wont crack in sun, i think, it shouldnt lol
