I just got my factory underbody kit, the front and the side are on great. The rear piece goes bolts on... but there are a few portions that have a gap against the car. Any suggestions for an adhesive to go between the gaps?

if u put them on right, there shouldnt be any gaps, do u mean where the spoiler overlays the lip?

I mean on the bottom part of the bumper... where the lip overlays it. certain sections have a lil gap between them

I also have gaps. The fit isn't all that great. Double sided tape might help. I might just upgrade my rear end to the Value Sports bumper

Wayne at Park Ave Acura states that if the rear skirt is installed properly, it won't have gaps and I would believe anything he says as he is very honest and knowledgeable. I installed mine myself and it had gaps. Since I have a DEP, you couldn't really notice the gaps. But with a little readjustment, I got rid of the gaps.

I picked up some double sided tape from Home Depot this eve... il see if it helps. The gaps arent that big, but im sayin... I know they are there. lol
