Rust product

[PJ.zook]

Ive noticed my rear wheel carrier RHS has gotten water inside it through a small hole i drilled for a rivet to secure wiring, i cant beleive how much water got in there thru that one little hole, but it did. Anyway, other than the hole the length of RHS is completely watertight. What i want to know, is there a product on the market which you can just pour in there and have it neutralise rust and maybe form a protective coating.
I know you can get rust dissolving acid, but you need to flush it with water and it doesnt seal.

fishoil would be the go....

Drill a hole in the bottom so you can drain the water out and then plug it up and fill it with a thick oil like slo-flo or even chainsaw bar lube(nice and sticky).
Once the inside is thoroughly coated you can drain the oil and seal the top hole where water/oil got in.(or leave the oil in there)
Never have to worry about it rusting then.

my rear swingaway bar has the whole end open. easy to clean out

Fisholeine or Lanotec pumped in there and seal it up with rubber plugs/silicone.

Any of the above mentioned by others will work.

Hmm never thought of leaving oil in there, good idea. Does it matter that theres already rust in there? If i put oil in there will the rust continue to eat away the inside or will it go inert?

Rust is oxidation...

if oil prevents air getting to the steel, then no rust... as long as you don't have dissimilar metals giving a galvanic reaction through the oil....

Maybe try something like rustbuster from hardware or kmart. Ive ussed in the past with good results. Some ppl use molassis diluted with H2O to convert rust.
then seal it up

A phosphoric acid solution can be used to neutralise rust. You'll get plenty of info from Google.

Yeh ive used phosphoric acid to neutralise a stack of rust in the back of the workvan from when the jump batteries developed a hole. Thought it was amusing that one form of acid (battery acid) caused rust, and another (phos acid) neutralised it.
I was hoping for something more like a liquid that i could just pour in the hole, seal up and slosh around, with the liquid converting all the rust and forming a protective coating.

If it's not too badly rusted, I'd go with the advice above. Something lanolin or fish oil based. Provided it coats all the rust and prevents air getting to the surface, as mentioned above, the rust will progress no further. Rust liquids on sale, I believe a large percentage of those are phosphoric based anyhows.

You could always drop something zinc based in there, but I'll admit to not being sure what effect that will have on existing rust, as to whether it works on that too or only on fresh metal. Also not too sure whether a zinc based solution would work the same way as pure zinc itself.
