you all that swear by fluid film need to look at cor-ban 35, it's the cats ass for corrosion prevention.being a aircraft mechanic, i've used it all. the thing with fluid film is it doesn't really dry, and doesn't last when exposed to the elements. cor-ban will dry in a few hrs to a hard coating, that can be seen through and will last a long time. only thing that will remove it is MEK and SKYDROL (aircraft hydraulic fluid, bad shit that will eat the paint off anything and burn the shit out of skin) pressure washing wont touch it (try pressure washing fluid film). if it gets scratched off you just reapply it. you just spray a few thin coats on a surface and your done. if you use it please wear atleast a dust mask and long sleeves, because it sprays in a fine mist and sticks to everything. i have seen it at HOME DEPOT i believe.
