Vintage AMT Posted April 30, 2022 Share Posted April 30, 2022 What is going to be my best bet for an adhesive to stick that grille surround to the front? Or, should I try to pin it? Thanks Quote Link to comment Share on other sites More sharing options...
Ace-Garageguy Posted April 30, 2022 Share Posted April 30, 2022 I typically use a slow curing epoxy (30 minutes minimum, though what I use takes 24 hours to full room-temp cure) plus cotton-flock to adhere dissimilar materials. Lotsa people think my approach is overkill, but my stuff never cracks and falls off...or cracks during sanding, polishing, etc. Quote Link to comment Share on other sites More sharing options...
Rick L Posted April 30, 2022 Share Posted April 30, 2022 Agree with Ace. It may also help to sand the mating side of the styrene with a coarse grit sandpaper. 1 Quote Link to comment Share on other sites More sharing options...
Plowboy Posted May 1, 2022 Share Posted May 1, 2022 I use crazy glue. If you're cutting an opening for the surround to fit into, you can still use regular glue from the backside. You'll still have a styrene to styrene joint. 1 Quote Link to comment Share on other sites More sharing options...

Never heard of this technique, but I'm gonna have to try it. Does the cotton flock allow the epoxy to be sanded like filler? Quote Link to comment Share on other sites More sharing options...

Here's an application similar to what the OP is asking about. The blue hood surround section was bonded in with epoxy/flock, shaped, then the grille section was put in, and more epoxy/flock used to form the fender cheeks below the headlight sugar-scoops.
