I just got a new raw round oil tank for the springer. was thinking of painting it flat black to match the pain, but was wondering if I need to seal the inside? or just clean out rust, prep and fill with oil?
I would clean it with acatone to remove any grease or dirt inside and go from there. Use a etcing primer and then paint. I bought a powder caot set up to do small parts and the results are great. And boy is that stuff tough. I am in the process of blacking out the deuce.
