I have some brake caliper brackets that I want to use on my car but they have a lot of surface rust and have been badly painted.

As they are I think they will start to look very tatty, and some of the surface rust is on the pad guides. I've cleaned them up a bit with a wire brush but they're still a bit of a state. I don't want to use them and find it causes the brakes the stick or squeal more - DS2500 pads are bad enough as is! They're structurally sound but need a good tidy up, and the wire brush doesn't seem to cut it!

Can anyone recommend a place that would shotblast them for me? I know its a small job, was hoping someone might know of somewhere/someone who'd do it for a few quid! Ideally in the west mids/wolverhampton area.
