What do you guys think about ABS panels for package tray and door panels?

Awesome, thanks! Screws sound so simple...but like a great idea. I know there are caps that can be put on with them, too. If I can do away w/those factory clips, that would be the best thing. I was leaning towards body clips...now I think I need to find some screw caps :)
When I go outside I will take a closer look, but I think the screws that were used on mine have small black washers under them as well.
