The original toaster tank on my 51k, /5 project has no rust inside but the OEM inside coating is showing its age. The outside will be re-painted.Having used POR-15 in the past on worse vintage tanks(inside rust) I was leaning toward another POR-15 job but now thinking Red Kote is the way to go? Any other ideas out there?
FWIW, one of the things you have to watch out for when you seek & try to apply information from various "tech Lines" such as mentioned here (but not meaning to point at POR-15's tech line) is that they are knowledgeable about their products but often lack "application" skills or knowledge. Don't expect them to know how to use the product in the shop as would a skill trained tradesman.
Another benefit with Red Kote is it has an almost indefinite shelf life if you seal the can after using it. I used the same can a week ago that I bought 12 years ago and it worked perfectly. I have some left over and will buy some more so I can do all the project tanks sometime this Winter before I get paint put on them.
Por-15 is some great stuff but its no match for the Red Kote!!!
