Ouch !
Hi there -I really do feel for you - Diamond cut alloys are a nightmare !!
Ive used these guys before - a chap called alex is very helpful.
Midland Alloy Wheel Refurbishment & Tyre Specialists Ltd
Unit 11
Premier Trading Estate
Birmingham
B7 4AT
Not a great place to look at - but they do a first class job .
I paid £85 a rim - If you want perfection.
Its a steep price ! but stripping and any alloy in fill - and powder coating - and wet finishing and diamond cutting - Its a big process .
Thats why Ive gone off 18 inch titaniums - I had these that cost the same for a mild scrape in a rebuild .
Now 18 inch performance wheels - that cost £45 to sort out.
That said - the 18 ins performance have never been scraped - but the titaniums -when some

comes at you and forces you to the take the kerb .... enough said !
Hope it helps !
