Grcamna - yes, I used SprayMax 2K; I've used it on my KZ400S to great effect. Here's a shot of the final product - it looks a bit orange-peely, but I let it sit and it's leveled out really nicely, the pics don't do it justice, it came out great; I'm very happy with it! I have some double-line white pinstriping like the OEM I'm going to add to detail it a bit to hide the rough edges of the black, but it should look really nice when I'm done. I got bored waiting for the candy to show up this afternoon and decided to dig into the carbs of the 550 I want to do next; they look kind of gross, but I've worked on worse...new jet holders are on the way, and at least all the jets came out okay; but then the paint showed up so I had to get that done first...but with the completion of the 500 tank, I think she's ready to roll! I used Rustoleum Semi-Gloss on the black part, and didn't put clear over that, but seriously, it looks awesome.
