So my new used right headlight had a broken tab but the smashed one on car which came that way when I bought it had one good thing - broken tab I needed. Just had to get creative with grinder and epoxy.

 

Nice! Have you ever heard of a plastic welder. They are pretty handy tools. That way you could plastic weld and epoxy and you would end up with a Belt & Suspender situation.

I am about to try plastic welding on different part. However this part actually has metal bits in the tab. Doing it this way actually has more surface area of contact. It is super strong now. The other parts will break before this JB Weld will break. Thanks for tip.

 

I like your epoxy repair, especially the use of the (fiberglass) reinforcement, embedded in the epoxy...thanks for sharing!

I don't have a plastic welder, but it is an interesting concept. I would be cautious using it because of the fumes, and compatibilities with the plastic welding materials. I may watch some YouTube videos to find out more. I remember watching a good Scotty video about plastic repairs years ago, which might be worth a second look.

 

100% on fumes. I use a inexpensive double sided P95 filtered mask from Harbor Freight works great. Use it in bondo and paint also. $15 - https://www.harborfreight.com/p95-ma...tor-66554.html
