Molding fiberglass skirts with 3M 8115
 
Would like to mold some side skirts on a car. Can I use 3M 8115 to mold these fiberglass skirts onto steel body?

Are these skirts permanent? If they are and you want to bond fiberglass to metal, then yes 3M's 8115 will work...Just be sure to finish your lap area with fine paper (I finish mine in 320 before priming) and allow plenty of cure time for the panel bonding adhesive...give it extra cure time...if not, I've seen the bond line come back and be quite visible in time after it's painted

I think I'll use Evercoat metal-to-metal body filler on the joints

I wouldn't use the metal to metal, the off gassing of the metal to metal on fiberglass could bubble down the road, I'd use short strand fiberglass by evercoat, more compatible with both surfaces.

Isn't metal-to-metal a fiberglass based body filler? That's what my auto body teacher said. He was mad when I've used it in shop cause of "fiberglass dust everywhere"

Actually it's aluminum based and uses fiberglass resin, the off gassing comes from the aluminum...metal to metal is the same principal as a product called aluma-fill. Like all Ski-do's are snowmobiles but not all snowmobiles are Ski-do's.

Your teacher should have been more upset about the aluminum dust, alzheimers related problems with aluminum.
