Suggestions on sprucing up these RD's

[shellback]

Could you post some ideas of rejuvenating these RD's?
Blast them and powder coat? Paint? Looking for the most durable finish but do not want to affect their integrity.
Thanks.

If your looking for the most durable finish have them blasted and powder coat them.

Just know that blasting is not the best way but most places use that. It does affect (it is a trade secrect). There is something that is called cold blasting that is safe.

I've also heard soda blasting is supposed to be gentler
