I am a painting contractor and have tried every variety of rust preventative. Although no product can keep rust from bleeding through eventually, RR has proven, over the course of many years, to be the most effective. I recommend a double coat for maximum longevity. For really fussy jobs, I add a topcoat of Dr. Rot Epoxy Sealer.
