quarter panel replace ment

You don't flange panels or bond panels at seems.Bonding with epoxy will show a small shadow line at the seem every time.It is the **** when bonding along pinch welds around wheelhouse,window pinchweld.Flanging is a no no it will hold moisture and won't allow you to finish the seem properly with hammer and dolley.if you are having problems butt welding such as warpage slow down walk away.3m is the best product hands down 8115 is the product that can fix anything.8115 is the duct tape of epoxy.SEM weld bond is problem prone with panel seperage and shelf life.Lord fusor don't even think about,ask the big three about some of those issues.8115 was a product from a company called duramix wich 3M bought out just for this product only.They couldn't duplicate it,so bought it.20 plus years experience of using this stuff everyday.By the way 3M has a manual gun for 35dollars and 3M and SEM use the same gun
