Best Bonding Adhesive

[565bbchevy]

I bought an aftermarket 3 piece fiberglass rear deck spoiler for my Regal project and I need to bond on the ends to the quarter panel extensions and I am wondering what the best product to use for this application is.
Tips and tricks welcome since I usually do all my "bonding" with a welder.

565,
This is probably your best bet,

as it will bond damn near anything to anything.

Be aware however, you'll likely have to do some sort of prep to the areas the spoiler will be bonded to. The substrate needs some sort of "tooth" for the adhesive to hold on to.

I don't think 3M recommends applying this to painted surfaces, but that's more for 100% bonding strength for structural purposes (as in attaching quarter panels etc).

For what you're doing, I'm sure you'd be fine with just roughing up the surfaces with some rough scotchbrite pads and applying the product.

I'd be sure to find some way of clamping the pieces securely in place until the adhesive cured tho.

I've also used 3M panel bond with good results. There are cheaper alternatives that also get it done.

Is that the stuff manufacturers are using on the assembly lines nowadays?

I was gonna say epoxy too as it glues everything pretty much permanently, but then I saw you said q-panel extensions. Are they fiberglass too? If so, then fiberglass epoxy resin is probably better. Just roughen up the surfaces until the glass fibers are showing. This is where marine products come in handy and there are small kits like this from West Marine designed for a quick repair without purchasing a huge amount of material. But if they are just some kind of plastic then regular epoxy may be better.

This stuff is strong when I worked in a gm body shop at our local dealer we used this to attach the side of a van

Evercoat is good stuff. I've used it on bumper facias and steel body components. Check out the link

No build thread? 🙁

I will probably start a thread later when I get farther along, it's moving along kind of slow with work being so busy I don't have a lot of free time and so far only rebuilt the brakes and suspension and installed the new seats, nothing all that interesting to look at.

You might want to give loctite a call, or go to aa dealer and speak to a rep. They have so many products, i couldn't begin to tell you about them.

At work, we started replacing some of our welding processes with bonding. So strength would be zero issue. But you have to get the application right.

You might even get lucky and be given a sample to try...
