Thanks for that.
Yes, please note that these guys are Powder Coat specialists, if your rims are a bit worse for wear, like dented, nicks and scratched etc, they will only sand blast them, you will need to get the dents repaired etc elsewhere, they will do the sand blast and powdercoat.
They are called Rodman Brothers, their Tel No is 02083618553. They are real nice people, there is a tyre shop just across their unit, who will remove fit and balance the tyres. Also very nice and friendly people. Ensured that no scratches were caused during fitting.
So, If you want to get the powder coating done on your wheels, pay a visit and talk to them, mention name as a recomender, (which is Kamal) and you will get the best deal. They charged me £200 for 5 rims.
All the best.
