Wet Sanding

[Winky151]

Colleagues car got covered in blobs of what I'd imagine were limescale (underground car park with rainwater from the floor above dripping through) which he pretty much removed with Cillit Bang or such like but in trying to get the marks off initially left some scratches which I've offered to go over with my DA. Actually saw the scratches today & reckon they may even need a bit of wet sanding - what would be the lowest grade of grit to use/what grades to use?

TIA

Cheers guys.

Intend to go with the DA first but wanted to get my grits right in case they were needed.

If it is just like scale, why not just use a lime scale remover? I use a gel tyre product, brushes on and rinse off.
