The black tar paint sounds like a good idea but, doesnt the galvanising zinc
paint work by being in direct electrical contact with the steel, the zinc is
a more reactive metal than the steel so it will allways react, oxidise,
whatever, before the steel. galvanising or spraying with zinc paint is rust
protection that works by sacrificing a more reactive metal to oxidisastion
in order to save the steel floorpan. Therefore, if you spray zinc paint over
rust converter, wouldn't any galvanic rust protection be negated because the
rust converter would be acting as an insulator between the steel and the
zinc???? Thomas..
