I'm getting ready to start putting the interior back in my car that was supposed to have been sprayed with SPI epoxy primer about 6 years ago when the body work was done. I know SPI was used after the car was blasted but I am not sure the repaired floors were done with SPI. I am getting ready to install Fatmat and if installing over SPI I have no worries but if the guy doing the body work used regular primer for the partial floor replacements I feel like I should topcoat those areas before installing Fatmat. Is there a sanding or scratch test I can do to verify the primered areas are epoxy and not regular primer? Or is it no big deal if I use Fatmat over either primer? I'm concerned with moisture if regular primer was used. Thanks, Mike
