Powder Coating Question

[wheelsup351]

A few years ago I had a pair of high dollar fab'd valve covers powder coated. They look good and I've gotten quite a few compliments on them.

I need to weld in another bung so I'm tasked with either re-coating them. Can I remove the coating with aircraft stripper? I've never used that stuff but I have it.

Is there anyway of restoring the polished look that the covers originally had before I had them coated?
