I just purchased a 2014 Alaskan co and drove it back to Fla from Co. I noticed that on the two side panels of the co there was a area where the paint on the siding was wore down to the metal. It appears that the wooden blocks that are on the large panel that hold the side panels up are rubbing on the side panels in the down position. Has anyone had this problem or am I doing something wrong. Is there a way to prevent this. Thks for any input on this. Also what type of paint should I use to paint the two areas.
