Well, my results with 'ph Down' are quite mixed. I've got a glass jug with a 10% diluted solution in, and that does a reasonable job of cleaning up stuff that gets dipped in it overnight. I've tried a couple of areas of bodywork and painting on first the diluted solution, and then the neat liquid, and it's still not shifting some of the thicker bits of rust.

I've been painting some on, leaving it for a while (overnight, on one test occasion) and then going over it with wire wool, then a grinding wheel in the dremel without putting too much pressure, and there are still some bits that aren't shifting. It's in a corner section, so I can't get the knotted-wire-brush-in-angle-grinder in there.

I'd love to know what the likes of SPL put in their tanks, and whether I can just paint some on my floor.

Hi Mike

I got some from countrywide.

Cheers Dave, will have a look there.

I am mixed on this stuff. The corner section I referred to above has now consumed so much time trying to clean off rust by dousing with phDown, leaving for a bit (sometimes overnight), scouring with wire wool, wiping off and going over with the wire wheel and/or dremel grinder, that it probably would have been quicker to cut the piece out, make a new one, and fit it. Yet in other sections, it's very good.

Still, even at the price I paid off eBay, it's way cheaper than buying a 'proper' rust killer. Just have the dilemma now of whether I should strip back some parts I've already done with Kurust and painted over, and do them again.
