I purchased a Retrax retractable bed cover. The problem I have is the heat. This black cover gets so hot that one cannot hold on the to the handle to open and close the top. I had my Yeti cooler in the back and it got so hot that the cooler cover warped. I inquired with the factory about painting the Retrax white and was told if I paint the cover it would void the warranty. I can't see how a thin layer of Dupont Imron paint could have any effect on the cover so will do it anyway. If the paint destroys the top nothing lost, just replace with something else.
