Coating).
When stripping off the original finish of my 57 Chevy I encounter a lot of mild corrosion in the surface of the metal. It was mostly black or dark grey, although some areas also had a light brown tint. It was impossible to remove with a DA and 80 grit. It was also impossible once DA'ed, to be felt by touch.
I got over in the original 57 section and found a great description: "tight corrosion." Recommended treatment was Dupont 5717S and 5718S, a two part system - and then an epoxy primer followed by two coats of 2K.
I got some, and after testing on a recently blasted metal part (has show no rust in over two months) applied it earlier today to the 57.
First, I finished the entire car with 80 grit and then 180 grit and then wiped it down with lacquer thinner. I then applied the products as directed, using a scrub sponge to work the solution, and worked hard to keep the surfaces wet until time to remove with water (per directions). However, I still got some streaking, probably caused by water runoff "thinning" some areas before the solutions were completely removed. Excess water was wipped off using good bath towels (they are in the washer now) and then the car was rolled back inside a heated garage with a continuous run dehumidifyer.
Finish varies from a light bluish/gray to a light tea shade. The "tight corrosion" areas are brown.
Is this the results that I was supposed to get?
Should the brown areas be retreated or is this what it is supposed to look like. I am ready to start spraying the epoxy but thought that I'd check with the panel first.
