Hints on hood hinge fiberglass repair
57 hood-previous owner broke hood hinges and anchor plates out of hood. He stuffed brown paper bag behind, and poorly reglassed. They broke out again prior to my acquiring the car. How do I support the anchor plates and reglass so they don't break out again? Any tips/successes would be welcome.
Thanks

I would recommend separating the hood skin from the frame and repairing the hinge area from the inside. I think that is the only way to get a sufficient fiberglass repair to the frame, and then you can install the bolt plate with soft aluminum rivets properly. Then, glue the skin back to the frame and be good to go. Lots of work, but the only way to do it properly.

I use this method taught to me by Mike Coletta....
-Cut a slot along the side of the boss where the nut plate resides.
-Make a template of the locations for the holes for bolts and rivets.
-Drill out the nut plate rivets.
-Remove the nut plate through the slot you cut on the side of the mount boss.
-Remove old repair materials.
-Bevel edges of "good" glass.
-Install a wax paper cover flat thin wood "backer".
-Build up layers of mat & resin into the beveled areas,to the correct thickness to match original build up.
-Remove "backer".
-Use previously made template to drill holes for nutplate bolts and mount rivets.
-Re-install nut plate through side slot and rivet into position.
-Fill slot with mat/resin mix.
-Sand & refinish repaired area.
Done

Brett and I repair them by sectioning a new peice across the front
Brett makes the front hood section with new backing plates
I cut the entire section off and replace the section

It's a lot easier to repair under reinforcement panels by cutting out a section of the outside of the hood and then reinforcing the braces.
There is enough room to apply plenty of fiberglass without changing the final look.
Then just feather edge the outside hood piece and laminate it back in place.
This allows repairs with out distroying the inside "originality" look.
