Heaterbox Pipe Passthrough - Reinforce vs Remold

A bondo fiberglass kit with the mat will fix that up.
You can scuff and go over the entire area and down around that corner, and then cut the holes again.

I had considered that, but I haven't done any fiberglass before and I'd rather keep this repair simple and get it back in the car. It's freaking cold outside!

that new light activated stuff, 5 second fix, might work there. I would use something to fully fill the screw hole and drill a new one.

I was definitely planning to fill and re-drill the hole. I've heard of that UV activated resin, but never used it. Do you have any personal experience with it? I wonder if it would crack or flake during drilling.
