Discussion
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

There shouldn't be any need to go below 1500, then work up to 2500 or even 3000 before polishing out.
Having said that, I would try to avoid wet sanding the area and stick with the DA. If the scratch is deep enough to feel then you're going to be risking sanding through the clearcoat by the time you've removed the scratch if you don't have a paint depth gauge to hand.
Since the paint is likely to have some orange peel to it, then wet sanding in the scratched area is going to remove that and it'll no longer look quite the same as the rest of the panel.
If the scratch is too deep to remove then the DA will hide the marks better by rounding off the edges of the scratch, whereas wet sanding will tend to leave a sharper edge that catches the light making it more visible.

Don't sand. Easy to go just that little bit too far & if it's a metallic/pearl break through the clearcoat or go through the clearcoat subsequqntly with the mop. Once you've done that it's game over & repaint time - on a car that isn't yours you've then got a problem!
Just mop, go easy with frequent checks & be happy with taking the 'eye' off it.

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.
