Quote: from my experience with different products, EVAPO RUST is the stuff to use. for a 5 gallon pail its about $99-115 depending where you buy it.
the best price i found was at my local harbor frieght with the 20% off coupon it comes out to 18 bucks and change a gallon. i wish i could find it local in 5 gallon pails. the shipping is what makes it expensive.
to control flash rust when i take the part out of the evaporust, i just rinse with water, then i take a hair drier and dry the part as fast as i can. thats the whole key if you let the water sit on the part and dry on its own then it will flash most of the time. i never have had any flash rust ever doing it that way if i'm not going to prime the part right away and its small, i put it right away when its totally dry in a ziplock bag to keep the air off it.. some stuff i have had sitting away for months before i primed it and i have had zero flash rust problems yet doing it that way..
