i used this on a landscape trailer 18 ft long worked real goo d saved a lot of prep work to paint
I have used several different brands,Extend,Rust Reformer,Rust Cutter,Rust converter,Rust Fix,plus others I can not remember .They work some what but this stuff really does the job.And its even cheaper!Its the only one that turns all the rust Black!I use it on bulldozer,tractors,trailers,truck frames and tractor implements.[...][$]
This stuff works great for cleaning out your motorcycle tank. Just remove loose rust 1st...ie. using a box of BB's...shake them around in tank. Then clean with Ospho. Tank is like new inside, no carb problems! I would recommend this to anyone!

I am using Ospho on anything steel on my boats. It seems to work great even if you are not painting. This stuff seems to neutralize existing rust. You can apply it with a brush, but I prefer to put it in a spray bottle and just spray it on. You do need to protect surfaces from over spray or run off. When it reacts with the rust and runs off on to a porous surface, it can be difficult to clean up. One of my sailboats has a metal drop-down center board, on which it really made a difference.
