MH50 On that paint,havn't heard of it but probably be fine. I used por 15 on a set of split rims 20 yrs. ago still fine but have been indoors that whole time. I needle scaled them till they were not shedding much 2 coats of por 15,had em put the tires on they aired-up to 45 lbs.Here we have sharp soy bean stubble after harvest that can hurt tires,have learned to pump em up kinda tight to combat that .
