After cleaning and prepping a tpo plastic bumper cover, I sprayed two thin coats of rattle can Ad pro followed by two thin coats of spi 2k sealer. The following day I wet sanded some orange peel and exposed some small areas back to raw pto. I attempted to spot spray these areas with some Ad pro and the surrounding sealer wrinkled. Two different brands neither of them spi had same result. This is not a feather edge issue. I suspect the sealer was not fully cured. 24 hrs at around 60 degrees.
I have since let the bumper sit for three days before I try again. My observation is that there is a lot of solvent in these rattle can ad pros. Yet most people discourage using solvent based cleaners on raw pto. This seems to be somewhat of a contradiction. Can someone please clarify why solvent cleaners should or should not be used prior to recoating a raw pto bumper cover?
