Sanded surfaces w/ 320 to scuff them, cleaned w/ acetone... and gooped away... this shit is hard. I put a layer around the hole in the mount, then under the bolt head and dropped the bolt in taking care to keep the treads clean. Pressed the bolt all the way down until it got a little stickey then coated the head and around it in more epoxy. Haven't torqued it yet... still in garage. It's a very hard bond... I can't pick at the stuff or turn the bolts by hand at all.

 

I'll pretend you didn't actually do that on your race car..

All you need is enough strength to hold the bolt until the friction is high enough to hold on it's own. I wouldn't have put any under the head though, if there is an appreciable thickness of epoxy it will compress over time and make the bolt loosen up. Should work fine though. I'll write this off as "temporary fixturing", but I'll kick you square in the nuts if you use cheap filled epoxy or JB Weld for anything more important than that.

Good to see stuff moving along, can't wait to see some race pics..

 

It'll be fine... all the epoxy around the bolt head will stop it from turning so if I ever have to tighten it I can. Also, lock nuts are being used. Plus the front bolts are ther and the seat back brace ties it into the chassis. It'll be all good

 

It worked.... seats and new harnesses are in.

 

Awesome! haha...
