What adhesive for C7 aperture panels?
Hello,
I'm doing a wide body conversion on my '15 Z51 by replacing the body panels with Z06 parts, including the front fenders, aperture panels, rear quarters and rear bumper cover https://www.corvetteforum.com/forums...n-project.html and I have two questions. First, after cutting away the old apertures, what is the best way to remove the old adhesive from the frame? Second, what specific adhesive product should I use when reinstalling the aperture panels? Thanks for any help.

A heat gun will soften the adhesive so it can come off....BUT.....you have to know what you are doing in some areas where the thickness of the adhesive makes replacing parts EASIER....because GM had already set up the thickness so gaps of panels are PERFECT. SO...removing ALL the adhesive on some panels is a BIG NO-NO!!!!! Or it will make it harder for you when you go and set-up a new panel.
AS for the specific product will depend on the metal of the frame where bonding adhesive is applied.
Many companies offer the adhesives...such as LORD FUSOR, SEM, ASHLAND CHEMICALS "Pliogrip"...and each of them have requirements on the type of finish their product gets applied to.

Some manufacturers want bare steel and you make sure the bare steel is covered with their product...some want an epoxy primer and lightly scuff it. SO...it depends.
I do not yet have a C7 service manual. But I can look in my C6 Corvette service manuals and see if they specify anything specific for the rocker panels. I do know GM does usually spell out a specific product..but also add "or equivalent".
You REALLY need to watch HOW you prep on these panels and DO exactly what the manufactures states. If they say 'scuff' then scuff it....if they say grind...then grind it. because it has been a long time since I have had to write this...but REMEMBER it is that 1/1,000,000th of an inch of crap on the surface...or improper surface prep that will cause for a product to loose adhesion.
