I guess thats why I decided to fill the imperfections with the 3M epoxy instead of epoxy primer. It adheres like crazy to the endura, it's flexible, & will fill the imperfections quicker than the primer. I feel I am still sticking to what paul has stated works on these bumpers, just using more 3M epoxy & sanding more on the front side & less epoxy primer on the backside. (hopefully) I did order the SPI epoxy primer, I found a NAPA distributer that ships about 100 miles from me.
Greg, did you wet sand the 3M epoxy, or the epoxy primer? I am looking to wet sand the 3M epoxy, only because it will be easier to see what I am doing.
