I used it on my kframe for our 69. Put it on outside in summer. Goes a long ways. Havent put the kframe in yet. So no review on durability but it's been kicked around the shop a few times, no chips or peeling. Fingers crossed.
I agree. All primers need tooth on bare steel. Paint manufacturers recommend #80 under epoxies and other DTM (direct to metal) products and the bare metal needs to be coated within 8 hours or microscopic rust will be too much after that. Low humidity conditions will widen the 8 hour window. POR15 encapsulates, it does not "treat" the rust like conversion products. 2 totally different products.all paint will peel when coated to smooth metal, the surface of the metal needs to be roughed up with scotch bright or sand paper for the paint to have something to hold and stick to.
my experience with por 15 has been that it did not stop the rust.
I hear you.....Unfortunately, I have to deal with realism........Building what I've got.But what I believe most of us are interested in is a classic Mopar that has NO rust and is painted and coated with whatever properly that it never does rust. Being unibody cars, even if the car has some rust its structural integrity is compromised to some point depending on how much rust it has.
