Bought some of this the other day, 250ml for £9. Supposedly used on North Sea oil rigs so should be fairly competent at the rust spots on my car. Anyone else used it? Comes in a white bottle similar to Vactan.

Yup.

I bought a bottle a couple of years back and still working (very slowly) through it. Seems to do the job. Similar sort of stuff, really. It goes on blue then turns very very dark blue once it's dry.

Wonder if you can fashion an mx5 out of it.

^^ Yes, yes you can.
