Soundstream,
There's one in Berapit, Bukit Mertajam. I lost the business card already. If you goto BM, just ask around the tire shop, they will tell u. Basically it's a Dunlop tire shop, specialized in paint and repair the rims. The building is painted in yellow.
I apologize for not being able to provide you with the exact location and the contacts. I sprayed and repaired my rims there 2 years ago, the taukeh charged me for RM160 (2k black, 4 rims, including the fees of repairing the dented parts). It took 2 days to complete. At the meantime, he will borrow u some shitty 14" for you to use.
Good luck bro. :D
