strip off the pares and have it re powder coated ..
I had a front rack* re powder coated,
he just roughed up the surface and applied another powder layer,
the old and new combined at the melting point..

* 1st job was hung with a wire Christmas wreath frame project batch,
2nd one was done with another powder coating project , gloss, black, this time ..

by having a friend involved, , each job was free..
though, 2nd time, it took a year for another paying customer
wanting the same color..

Electric power to heat the small room sized oven is the main cost..
