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. Here's what comes with the SEM kit:
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:
The first step is to clean and mask everything you don't want textured. Areas that will recieve the coating will need to be sanded and then recleaned. Use acetone or thinner and wipe down everything. The pictures below were taken before I cleaned the areas. In my case the entire area has been blasted and coated with epoxy primer. So I don't need to worry about much sanding. It is very important to have a clean and abraided surface.
While this is sold for home use, you will still need some equipment. The liner material is sprayed on using a Schutz gun. You will need the gun, a compressor, and a respirator. I'm using this product for the first time on the inside of a 1938 Ford cab. This is what a Schutz gun looks like:
