I am getting a hand sized web of what look like fine white cracks on the roof of my Black '95 Z28.

I think it may be more than just problems with the paint. I realize that the roof is SMC.

Has anyone else seen this before, or have a method to repair the roof panel?

A search on roof cracking didn't find anything on this board.

Thanks

Thanks for the replys.

I did a little more checking on what SMC is. It can be treated like fiber glass.

Since this appears to be surface cracking.

I would think that grinding the area down and applying some fiberglass vail and resin followed by a thin coat of bondo would be a sutiable repair.

The fiberglass should stop the cracks from showing through and bondo would give a smooth surface for painting. At least until the bondo shrinks.

On the 4th gen, the whole roof is SMC the metal is under that and the plastic pannel is attached with a urethane adhesive. So as far as I know the metal is fine and welding is not needed. You are right that the crack tips are the critical area. This is true even in plastic.

Sound resonable to you guys?
