While the bedliner is a great idea if you have it tinted the right color
to match the color of your vehicle , from the contents of the web page
you presented you mentioned painting  color on top of the already cured
Bedliner.

How are you going to do that?

This stuff dries like a rubber brick, and will be tough to prep to
accept paint after the fact.

How do you prepose to accomplish this?

Just curious.
