I'm looking to have my tips painted as well with high temp paint. However, the stock finish on my S-type tips seems very smooth and my paint guy was suggesting that we etch the area that I want painted with some kind of acid first. Another guy was saying he'd "roughen" or scratch the surface up first to help the paint adhere. Ideally, I'd like to just paint it myself as is just use a prep spray, primer, paint, then clear coat. Any suggestions? Also, has anyone used the VHT Flameproof paint system before???
