Here's how to repair a fiberglass panel the correct way.
The fender has been cut with an air sawsall but this would also apply to a crack. The alum angles in the pic are to keep the panel in place since the fender was pulled back 1/4 inch and there's a bit of tension on it (the crack would widen up if these were removed. The first thing to do is V-grind the glass out to 1 1/2 to 2 inches on BOTH sides if you can get to the back side. The very edges of the crack should be paper thin and you need to expose virgin glass for a good bond. Attach file: 1.jpg (0.00 KB) |

On the back side put 1 or 2 layers of glass mat. Since this repair was horizontal, the mat was applied and covered with 2 inch masking tape to keep it in place. Almost guaranteed to fall off while curing if you don't use the tape.
Then start layering up precut layers of mat. The first should be less than 1/4 in. wide, second 1/2, thirs 1 1/2 and last, 2 in. The people on the other forums who say to leave a depression for body filler are incorrect. This will result in a weak repair. The fiberglass in the pic is at least 1/16th higher than the body skin.

This is after the initial grinding with a 2 in. disc and then using 60 grit on a Dewalt 1/4 sheet orbital.
Note that in the first pic, there will be no body putty applied. There will be a thin coat of glazing putty to fill in the air holes and sanding scratched. The thickness of glazing putty will be way less than 1/64th inch when done. Attach file: 4.jpg (0.00 KB) 5.jpg (0.00 KB) |
