I do metal refinishing on the side but use chemical coatings like parkerizing, not painting. You see my kind of finishes on tools, gears and a lot of ferric steel stuff. I need help on understanding the different kinds of paint used on trucks. Polyurethane, urethane, enamel, etc. What works or doesn't work with what? Starting with self etching primeres, so called 2K primers, right up to clear coat. Is there a site I can visit to try and understand all this. I retired from a facility that did nuclear physics research. That was easier to understand. At least there they told you what was in a can, not that it was bad for you in seven different languages. Thanks for the help
