C3 header bar repair
I had my 1970 Corvette restored. Part of the process was to repair the nose bumps caused by the rivets related to the header bar. I instructed the method to be used as outlined by Wilcox (do not drill through the nose fiberglass). Unfortunately the restorer did it his way and drilled out holes to remove the rivets and then repaired. Now with summer heat holes beginning to show up under the paint. I know it will get worst. So the damage has been done. At this stage, any correcting repair advice? Fillers or bonding that will not allow holes to come back?

Hi B,
I feel the best fiberglass repair is to use the same method as used for filling holes on the rear deck from a luggage rack.
The fiberglass should be V'd out to the size of silver dollar. (Remember those?). Then the holes must be filled with layers of fiberglass mat and resin. No filler of any sort can be used, even to finish. It must be a 100% fiberglass repair.
Good Luck!
Regards,
Alan

That is a great lead Alan. This is a quality shop and a stand up guy. There is no question that he will attempt any new approach. He has already sent me two emails reminding me he expects me to come back to see the effect of the summer heat. Overall the rest of the work (very extensive-fame off) is top notch, which is why I picked him. He just thought his approach to the nose rivets would be OK. Bad decision.
This does look like what I had in my mind, don’t fill it, re-fiberglass it! I will share this with him.
Now that yours is done, how is it holding up?
