My GXP is rather new and just gets the Armour All to clean, but my 94 Ram 3500 is a different story and all the polymer restorers have a small life and the chalky vinyl shows right back up especially with an older dark Maroon. I use the Vaseline on all the interior in it for several years now and love it. It kind of attracts dust but doesnt need much reapplication and cleaning it back up is just a couple paper towels.
Just Latex Huh Bill? Guess there are some rubber items you should avoid putting Vaseline on
