Glasco gb50 rack. should i powder coat?

[loman4ec]

What do you all think I should refinish the slider rack in my glasco. I was going to zink plate but I can't find anyone local that does it. I just read a thread that Jim wrote about powder coating the insides of uprights being a standard. Should I do the same to the slider rack? Also how much should I expect for this to cost?

Powder coating is highly recommended because of chip resistance. The place I go to has a minimum charge $75.00+/-Sandblasting is extra.    DO NOT powder coat the aluminum flapper, it doesn't like the heat.
      For the same price you can also coat the shelf and doorliner, and any other parts you might have around the house.
