I striped the Bad rim down to Alum. By myself $175 in striper and 1.5 week of soaking and scrubing; w/wire brush and scraper. (the striper is recyclable if any one needs some)
My work gets lots of parts power coated so as long as I used a color that they had it was Pro-Bono.
Powder is purchased by the Pound Min. order is usualy 2-5 lbs depends on color. (if you are good you may able to get a sample pack usualy under 1lb)
There are 3 basic types of powder each having its own propitys. Any will work. Note:this dose not include the New plastic powder.
In my area I have heard of rims costing fron $75 to $150 per rim.
Hint have then coat I/S & Out. My guy only did the Face.
But I realy could not complain.
Attached are pics of new back in 03
