I am having some chipping problems on some suspension pieces that I coated with the chassis restoration kit components. I am using the aerosol version. The parts were bead blasted and/or cleaned with a wire wheel and then sprayed with rust converter. 2 days later I sprayed the rust encapsulator (red), and a day after that I sprayed the extreme chassis black. This was a good month or two ago.
In just moving the parts around the garage, the slightest bump against anything hard results in a chip down to bare metal. What can I do to get better adhesion and a more durable coating?
