As some of you may know from seeing my posts that I purchased a 79 RS that had been neglected. Stored outside, different numbered carbs, mismatched parts to say the least. I'm not complaining. And I don't mind the challenge having never owned a Beemer before. It gives me something to do over the boring winter months. Many thanks to the inmates for your help and experience. I have now turned my attention to the wheels. The rear is gold, front is silver with plenty of discoloration. So I have decided to powder coat them. My local guy uses sand-blasting before powder application. Should I look into something less aggressive? His work is amazing, and he has a strong clientele. Link to his website... http://www.quyscoating.com/?page_id=124 He says the sand-blasting shouldn't be a problem. Since you guys have more experience with these wheels I thought I'd throw it out to the forum. Thanks again in advance.
