Ospho quantities and type

[Rochey6957]

Hey bus folk, I see on amazon there are two different types of ospho sold by the gallon. A green ospho and a blue ospho. What's difference? The green stuff seems to be a few bucks more expensive.

Links!!!!

The blue stuff.

The green stuff.

Also how much did you use on your bus? How long is your bus? / Approx, how much rust did you treat?

Thanks for the input folks!

They are the same thing. There is only one ospho, one is just using an updated product picture.

Depends on how much rust you got.
I'm on my second gallon, but I go crazy with the stuff.

We have an 86 international with a decent bit of rust behind the rear wheels causeing the chair rail to seperste a bit.

And behind the chair rail...

I thought I had found a good deal from sears for $77 for a whole case... But its $200 to ship [emoji14]

Where are you located?
Every hardware store has ospho or something like it.

We got some at Ace. There was only one in Cincinnati that carried it. Couldn't find it in other hardware stores. Searched inventory online.

Rochester NY! 14623. I'll have to double check if our local HD/Lowes stores have it in stock

Any phosphoric acid-based "rust converter" will do.
