Has anyone painted a KOTT grill cover? If so, how did that work out? What procedure did you use? Anything special about the paint? We were figuring on Rustoleum with maybe a clear coat on top. Also, we wondered about the need to screw the mounting blocks into the bike. That doesn't seem really necessary if the adhesive is good and with so many blocks. We noticed the Slingmods version of the grill cover, and it only had two blocks, and it was just stuck with 3M tape. We appreciate any advice you can give. Thanks!
