Thanks Phong for the heads up. Since Ian was telling me that I should be using Krylon for intank painting, I am sticking with the brand. This morning I called OSH and asked about spry paint, the guy over the phone told me they carry Rust-Oleum. When I insisted on the Krylon, the guy got upset with me and think I was nut sticking to one brand . I did not explain since I did not want to confuse him even more.
