rustolium only prevents rust if its already there the rust will come back. por 15 is dangerious due to the iscoltites (I failed spelling in grade school!) and cant be sprayed only brushed and leaves brush marks plus its multi-steps. zero rust is great it kills the present rust and is safe to spray not very chip proof so I plan to top coat the zero rust with something harder on mine. Eastwood has some chasis paint that they say is chip proof and strong. Thats my story and Iam sticking to it! Later
