Hi in march I will be beginning my series 3 rebuild, it currently has an un-painted galvanised chassis and I will be fitting galvanised jackable sills. The galvanised parts will be treated with mordant solution then primer and finally tetrosyl chassis black. However I'm not sure what primer to use I've seen Hammerite special metals primer mentioned but other people say it dries too hard. I've also seen upol #8 but I don't think anyone's used it on a chassis so has anyone got any views or recommend a product?
Regards
Alex
