Buddy of mine did it to the tins on his yamaha, and it looks great. his only complaint is that he did flat black, and the texture makes it harder to clean. he actually left a stripe of gloss black down the middle, and if you wax that stripe and the wax gets in the texture of the powder coat, it's next to impossible to remove. just some food for thought!
