PJ1 is the best down pipe paint I've tried, make sure you wet 'n dry your pipes to scour the remaining chrome and get a smooth non-shiny finish, also don't forget to clean with carb cleaner or the like to remove greasy finger prints. Then two coats with two hours between, when dry, pipes back on your bike and go for a blast to bake it on.
The PJ1 Satin Black is also excellent for engine cases and silencers, same procedure but once painted and dry, put in the oven at 100c for half an hour, lovely job.
