Rust treatment

[thomp1983]

Looking at the sills inside the b posts im thinking about how to treat them. Most of the liquid options appear to be various solutions of phosphoric acid, fertans rust treatment gets good reviews but at £25 for a litre it's not cheap.alternatively i can buy a normal phosphoric acid for £16 a litre.

Im looking for something that will leave me a converted surface i can then plaster in cavity wax, liquid is preferable considering how difficult getting into the bottom of the b pillars

I've only been creating rust lately, so I'm of no damn help whatsoever! I have heard that cutting it out is the only way. You can slow it down, but as far as I know, you can't eradicate it once it's there. Products, snake oil or specialist treatments are just prolonging the inevitable. Is there some miracle cure for it?

Cutting the inner skins of the b posts just isn't going to happen whats there isn't too bad so hopefully i can slow it as much as possible but yes cutting it away is the best option everytime

Sand blasting will absolutely remove rust just get some zinc primer onto it asap to protect the bare steel, also waxoil
