Hey guys, I was gonna re-coat the top of my Patriot. I got up there and cleaned/scrubbed it real good. Cleaned the A/C's and all. Now, I was just going to do this because I just figured it needed to be done. Mainly because I don't trust anything the seller told me! Anyway, after I scrubbed and cleaned it up real good....it's not cracked or anything. It actually looks pretty good. I think I'll replace the refrigerator vent cover tho, just cause it's not white anymore. It's more of a yellow color from all the sun. So, I guess the question is how do I determine if/when the roof needs to be re-coated?? Thanks for any and all help.
