Re: Smooth Hood
Brian, out of curiosity is your shop BMW certified? Last I knew BMW was requiring certs in order to purchase certain parts like rails, quarter panels.
Would BMW even sell their adhesive and "bondo" to shops and guys off the street without BMW certification?
3M adhesives like 8115 and 8116 say no to bonding on exposed edges, for ex bonding a 80% quarter skin on. Fusor had a procedure for bonding butt joints using a backer but even they said ghosting will be visible.
I did a quarter skin on a 68 Buick GS about 20 years ago right when adhesives were hitting the market. 3M rep came in saw the Buick getting fitted for quarters, suggested we use 8115. I remember thinking afterwards, WOW what a game changer. Anyways, the car got painted a gorgeous deep dark blue, sat around a few months getting put back together. Car left the shop to get the interior done and would be returning once finished. Upon returning, the Buick was left outside in the late spring early summer sun for several hours. Car came back inside and that's when someone saw two horizontal lines running down both quarters right where the bonded joint was.
Endless to say, I've learned my lessons multiple times with panel bond. Great stuff when used in the appropriate application, but bonding a strip over a seem on a flimsily arse hood???
