There’s also the DIY method for spraying bed liner in wheelwells…I used U-Pol Raptor aerosol Bedliner spray that I got from AMZ (BTW, the “Raptor” name is just a coincidence)…I just used plastic sheeting & taped off what I didn’t want coated (it was easy), cleaned wheel wells really good, used the Raptor Adhesive Promoter first (also from AMZ), then sprayed the Bedliner on it…it came out really well & I am satisfied with it. Everybody thinks I had a shop spray it, it looks that good!
I ordered 2 cans of Adhesive Promoter & 4 can pack of Bedliner spray…didn’t use it all, but better to have it (just in case).
