to clear up things, this will only work on aluminum, if you have scratches in your bars, then you might want to sand your bars with 220 grit working down to 2000 grit. if you want to preserve you hard work and keep rust out, then use aluminum sealant.
Where the bars anodised or powder coated cuz I wanna do this to my anodised bars. Also just wondering will paint tripper work with anodised parts?? Please respond!!
