Applying A Tintable Catalyzed Spray-in Bed Liner
I’ve spent many hours determining just what to use inside the cab, under the cab, and in the bed of my trucks. There are a few do it yourself bedliners on the market but most are un-catalyzed and only come in a limited spectrum of colors. The best one I could find for home use is produced by SEM and can be located anyplace that sells SEM products or at the Eastwood Company. The kit costs between $125.00 and $150.00. 
Start by pouring some of the bedliner into the supplied bucket. I only mixed 1/2 quart at a time as I don’t want any waste. I’ll be using the rest on other projects. Add paint to the liner material. Use a ratio of 1:8 to start and adjust for color match from there. After mixing I put the material in the schutz can supplied and added catalist in that container. That way I can reuse the bucket for the next mix without fear of hardening. Use the insrtructions on the can for mixing catalyst. Spray the bedliner on using a pressure from 35 to 90 psi. The texture varies with different pressures. The instructions say to use three coats with specific wait times in between. Because I was using the product more for appearance than durability, I just shot two coats. The results are a very nice looking texture with a good color match and the durability of a catalyzed liner. Here’s some before and after pics:
