Powder Coating or Just spray Paint?

[cjbcpa]

I think there is really no other option than painting.

Unless the roll bar comes apart and/or you have a very large oven, I think powder coating will be difficult if not impossible. Getting the powder onto the roll bar will be simple enough but the next step in the process is baking it in order to cure.

My brother does this quite a bit and built a large oven using the heating elements from an electric oven installed into a large home-built box. It's a large as a refrigerator, but even that wouldn't take a roll bar unless it disassembles.

You will need to know someone with an industrial oven I think.
