hi pitrack 1
sounds like your having a lot of fun building something.
the phosphoric acid type of converter I have used has only stated not to use it on gal-zinc or painted surfaces as it wont dry , it only dries on the rust , after drying it can be top coated, but I always use zinc with no problems as a under coat first. the rich zinc paint is also sold in auto paint stores for use on rusted car bodies guards ,doors ect followed by top coats .
for me the best rust converter is the other stuff that turns the rust black, you can apply it over paint and it dry's to form a tough under coat, easy to use and does work stopping rust from returning .
rust is a real pain, having spent time painting no one wants to see signs of rust coming back through the paint again.
you can be real fussy and the rust comes back or at times do a car yard special and slap the paint on over the rust and have a long lasting paint job, o the joy of painting
very hard to get a good finish with a chrome paint most for me anyway look more silver than chrome.
it sounds like you want to do a good resto on whatever your fixing up.
its fun mucking around with things its the best way to learn things , hands on is better than staring at a pc or phone all day long .
ps hammer finish hides lots of things and looks great in blue
good luck with your project, and looking forward to see it finished
