What process shall I follow up with once de-rusted?
All the stuff I am doing is running gear on a car. I am thinking a kind of primer (etch?) and paint. Will use VHT stuff as I have brakes too.
Be really careful to rinse and rinse again. Don't want any acid leeching out later. I think you can make sure of neutralising with bicarb or something?
I bought a MK1 Focus estate rear cross member. It wasn't too bad when I got it but it sat on trestles in the garden under a tarp for a good while. I eventually then took off all the trailing arms etc and put it in the bath of citric...in Nov 2019. I'm taking it to the tip Thursday I think.
