There is a place on 34th st n, just north of 126th Ave n that does powder coating. He's not a small kitchen oven guy, he does big runs for Disney. I am pretty sure he will do it, but it will be expensive.

Here is a map of his place. I don't have his number. It's on the left hand side if you are heading north on 34th st n in st pete. I will try and get a name or number for you.

It's the white rectangle building at the very top of the screen on the left next to "34th"
