Used Hammerite to paint it yesterday, got the dreaded streaks so what i did was dip the brush in some white spirit, let it drain off slightly and then go over the top of the paint id already done, did the job beautifully. Cant believe i didnt think of just using gloss black, it makes complete sense now.
Thinking of doing the footrests next, but thinking i should get them powder coated rather than hammerite them.
