I’m restoring a very old equipment trailer and would like some input on painting it. I really don’t want to spend the money on automotive paint, yet I don’t want the thing to be back to it’s rusted state next year. I’ve looked at a few options and was wondering if any of you had experience with these items. One is called X-O rust primer and paint. They have a primer that can be used on rusted metal and it is suppose to stop the rust and prep the surface for painting. The 2nd I’ve read a little about but have not seen yet it epoxy primers and paint. What are your opinions? Any tips on painting would also be greatly appreciated; this is my first major paint project.
