My buddy has a set of Forged Aluminum wheels but they have been aftermarket powder coated black for a show truck.....He is wanting to remove the powder coating. What is the best way to do this and not screw up the wheels.
Just called my powdeercoating guy and he said that he would sandblast them. As an estimate he said about $40 per wheel for 15x7's. Not sure if there are other options or not. Maybe someone else will chime in.
The way we repowder something that needs new or different paint, is stick the parts in an oven and burn it off then just recoat. Not the cleanest process but it works for manufacturing. If you plan on recoating them whoever is going to do the work will take care of it. If you are repainting yourself have them bead blasted.
You might want to try some aircraft stripper, made by Mar-Hyde.
We have a methylene chloride vapor degreaser at work that will remove the powdercoating we use on someof our parts. It is worth a try, as methylene chloride is tha active ingredient in Aircraft Stripper, and most other paint removers. Check the labels of the cans to make sure....
