Additional powder coating questions

[Donnovan Sunrider]

I have a question regarding powder coating that I'm hoping the community can help me with.

**Edit**
I found the answers to my other questions.

Has anyone tried etching or scribing designs into the powder coat? I'm thinking of making a stencil and using a caustic paste to eat a layer of the color off to the metal under it for interesting designs, then applying a top coat to keep it intact. Anyone had any luck with such an endeavor? I was thinking of using the stuff you use to etch glass as the etching medium since I have some already. Any other methods recommended for such an option?
I'm looking for the ability to add some lettering and designs into the paint finish.
