Thanks guys. Just to update you all, the alloys aren't even TSW! I drove past an alloys and tyres dealer today to see if they could ID the wheels. After trawling old and new TSW catalogues we then took the wheel off, where a local expert then confirmed that it definitely wasn't TSW. This is all despite the auction stating the items as TSW. Oh well no worries...
Tony how much is the hot version that you do? Sounds to me like it would suit the alloys better to be put back in shape this way.
Also how long do these procedures take? I live down South London, and would ideally like to drive in and drive out in one day.
Thanks for the advice!
