Lord Products sells panel bond adhesive under the "Fusor" brand name. That's what I used on my maverick cowl panel.
Is the stuff sandable once its cured? I was thinking of using it to glue the spoiler to the trunk and end caps to the quarters to blend them into the body. Think it will work for that?
There probably isn't enough surface area on the spoiler or end caps to make a strong bond. Thats just my opinion but it may help along with the factory bolts.
I agree with John, not enough surface area. You can sand it too but primer doesn't seem to stick to it very well. Would probably have to use filler over it first. And it will be somewhat flexible therefore will eventually show a crack in the paint if you're intending on smoothing out the seams.
