68 barracuda 383s "Driver Paint Resto"

I looked up the CRE Epoxy primer. It's a PPG product, so it should be decent. Ask for a tech sheet on it, and see if you can do filler over it...and how soon, and does it need to be sanded first. Use whatever metal cleaner is recommended on the tech sheet to clean the car before spraying it. It looks like it needs a 1.4 - 1.8 tip on the gun to spray it. You should be able to just scuff your jambs and use the epoxy over the top of it if you want. Good job on getting the car stripped so quickly!
