I don't know if a wheel will fit in our blasting cabinet but I think that Pro-Coat in Tampa will be able to do it for you. Glass beading might not be for you, however, as it does change the surface a bit, causing you to go through a few extra sanding steps.

I've had mixed results with the spray. It's good for some surfaces while it lacks on others. Usually, I get the jug of goo, apply it with a foam brush and let it sit for 15-20 minutes in the shade. On the second coat, I do the same but I use a stainless wire brush to create more surface area for the remover to bite into. Don't use a brass brush as that will discolor the aluminum creating more work for you in the end.
