the rust preventitave paint is the one that you will need for the chassis, give it two coats with this, some people leave it at that but as the paint isnt UV stable i decided to top coat this with the chassis black also.
if the metal is new ie.not rusty, you will need to strip the paint off and spray the areas with metal ready to give the paint something to key to.
as far as quantities one quart should be enough to go around the floorpan top and bottom.
