Priming over bedliner

R

Ricker

Hi everyone, I'm new here and I'm also new to painting. I have a '97 Dodge Ram that I have completly disassembled and had the frame blasted and powder coated. The frame, suspension, and driveline are now reassembled with new or the original parts that was cleaned, blasted, and repainted. Now I'm starting the body. The cab is completly stripped. I drilled out the spot welds on the rockers pinch weld to open them up and drilled out the spot welds and removed the cab mounts. I cleaned and had all this as well as the bottom of the cab blasted. I got some SPI epoxy primer from someone off ebay and with this and some weld-thru primer welded everything back together and then sprayed the whole bottom and inside floor of the cab with the rest of the epoxy primer. I had some Upol Raptor bedliner so I also sprayed this on the whole bottom and cab floor. After I get some more SPI epoxy primer I want to spray the whole cab. I started sanding the exterior with 180 but I'M not sure what to do about the bedliner. How do I prep this to spray with epoxy, or should I not worry about spraying the bedliner? Will the epoxy stick to the bedliner without prep?
 
Lightly sandblast it, I don't know what else would work, unless it is smooth enough to Scotchbrite without leaving the low spots unsanded.
 
Thanks for the reply. I'll try some red scotchbrite and see how it works. I may have to leave it as is, no way I'll be able to get it reblasted. Thanks again!!
 
Well the kind of blasting I had in mind would best be done with a handheld unit, just wave it across the surface enough to where you can see that it's abraded slightly. But it sure makes a mess!

Scotchbrite is probably your friend here. Hope it works out!
 
I took some red scotchbrite to the cab floor and it did scuff it with a little effort. I need to get some more epoxy and then I'll get after the bedliner.
 
I didn't think he was looking to remove it or even change the texture too much, just wanted to abrade it for adhesion, maybe I was wrong about that?

Those wheels will remove material and make it hard to achieve a uniform look, imo.
 
Crashtech is right, I don't want to remove or change the texture, just need to rough up enough for optimum adhesion.
 
x2 ive used them a few times to do bedliners over a bedliner. i would at the least throw some adpro for a little adhesion boost.
 
This morning I got a roll of red scotchbrite from a friend, 4" wide x 20' long. I cut 6 pieces about 10" long, folded them in half, put a small hole in the center, and threaded them onto a 5" long bolt with washers and a backing nut to hold them all together. I put this into my air drill and went at the bedliner. Worked pretty good. After running this for about 40 minutes the floor was covered with red scotchbrite dust, it was every where. I'm glad I wore a mask. I'll have to get some epoxy primer ordered. Thanks for everyone's help!!!!
