Jimbo8v92 Posted June 25, 2021 Report Share Posted June 25, 2021 So i just painted my headers a few weeks back they looked awesome and after the first time letting it run to fill up my new radiator the paint started to bubble and then flake off. I did everything as the instructions said sandblasted, cleaned with reduced kbs cleaner, dried with compressed air, 2 light coats of aerosol primer, waited about 10hrs or more then 2 light coats of pure white, baked in a welding rod oven at 350 for half hour. I even took the precaution of letting them sit for a week before i put them on the motor and only ran it for a few seconds 2 or three times to give it a good heat cycle before i actually ran it. Primer looks fine under the paint, should i have scuffed the primer? I included a before picture and will take a picture later of what it looks like now.
