Front Cowl Crack Repair

Mine has a crack on the front cowl just ahead of where the hood latch is.  I know when I was shopping for my car in the 90's, I found several with this problem.  Has anyone on here repaired a crack like this?

If so, how did you do it, and what did you use?

Is the cowl fiberglass or some other material?

88,
I thought that the front panel was simply fiberglass, so any fiberglass repair should work on it. I wonder if these cracks are caused by overzealous hood closers.

Thanks for the vote for fiberglass.  I think the crack comes from folks resting their hands on the cowl edge and leaning into the engine bay.  

Next question: has anyone tried vacuum bagging the resin to draw it further into the crack?  I used to work around aircraft maintenance, and they would repair composites by rigging a vacuum pump with a suction cup to the crack.  First they'd draw the moisture out, and then I think they'd pull the resin in.  I should have paid more attention.  I've talked to a couple of the higher end shops in KC, and they've never done it.

Many, many years ago (1st TC) I thought putting my knee on the cowling, well I didn't think and cracked it about like yours. I took toothpicks to separate the crack and squeezed JB Weld into it.  Then I pulled the toothpicks out and pressed it back together.  After it set, I sanded it and got touch-up paint and came out hardly noticeable.

Just a thought,  Fred
