yes its expensive but it was always something i put on and then never covered up.. it wasnt meant to look pretty but was meant to stop further rusting..
all i typically did on the cars was a stiff wire brush after a 150 PSI air hose.. then painted it on... and I wore pretty uch a hazmat suit to apply it as ive been told if you get it on you then its there for good... i never took that chance..
I dont know how ospho is but sounds like i should try it where i need it on the carpenter bus in spots.. is it nasty if you get it on you or can it be removed with mineral spirits?
Its like slightly caustic water. Its like 40% phosphoric acid. As long as you don't get it into your eyes, its really not too bad. Breathing in the vapors while youre slathering it all over isn't too good. Make sure you wear a mask like when painting, or have good ventilation going at least.
Back in auto body school we used to get it all over us, its not really too bad.
Rinse with water and all is fine.
SUPER easy to use and works.
