Where's your location at buddy? If u are located in KL area, then pay a visit to Wan Sing Sportrims Services in Jalan 4, Sg. Besi & look for Ah Chai (boss) for quotation to get your rim repaired or spray painted. Superb quality with reasonable price. I've done mine there for the past 8 years, sent more than 10 sets of branded wheels for refurbishment.
