I had painted plastic fender flares on my jeep. I dont know who painted them, or what they used. I noticed it was somewhat flexable, but when rock would get stuck in the tire and sling out ... It left stars in the painted flares. I dont know if your rhino will have any reversed exposures like this. I was told that spraying "Rhino Liner" on the under side would have prevented it from starring. I painted a golf cart a few months ago, but it was tin. Wish I could help more ...
