Adhesives and adhesive use for Mopar body and heater box restoration
3M 77 High Temp Spray Adhesive
Available at any chain auto parts, craft store or art store is used to apply the charcoal foams in our heater box restoration sets. Though the factory used pressure sensitive adhesive on many of the heater box foams we found this didn't allow re-positioning of the foams.
3M 90 Spray Adhesive
Also available at any chain auto parts, craft store or art store is used to apply the firm charcoal foams on the exterior our AMC AC / heater box restoration sets. This is a very aggressive contact adhesive. For our heater box foams I recommend test fitting the charcoal piece first. Then after putting the foam back in the scrap it came in to protect the edges from over spray, apply a fairly heavy coat of adhesive. Install while the adhesive is still "wet" to allow positioning. As it drys you will quickly lose the ability to reposition the foam and once dried it will be tough to remove.
This adhesive also works for attaching shoddy pad (shoddy is the ground up cotton scrap insulation used under the cowl and headliner in most 60 and 70's cars) to the underside of the cowl or to trunk divider cardboards. Again do a dry run to test fit the parts before applying adhesive.
3M Black Super Weatherstrip adhesive (3M# 08008)
Available at any chain auto parts is used to apply black foam rubber gaskets used on some body seals, trunk weatherstrip, and some black foam rubber heater box restoration set seals.
The factory DID use a thin bead of black to hold many of the body lamp lense gaskets in place but this was ONLY to keep them from falling off during the hustle and bustle of the assembly line. This was not meant or needed to improve the sealing quality of the body gaskets. It also makes removing and replacing the gaskets in the future more difficult. For a restoration I would not recommend using any adhesives on the body lamp gaskets. Note: The factory used the yellow version (3M# 08001)
