A bit of petrol on a rag, wipe it all off, then give the panel a good going over with some polish.
(If you haven't got petrol, thinners will do)
Just wipe the soaked rag over the paint and it will be fine. If you start scrubbing you will damage the clear coat on the car.
2500 - 3000 grade paper and a da/ratary polisher + compounds/polishes.
Why go to all that effort? What's the point?
To get rid of the paint.
If anyone is in the same dilemma .. Daniel was spot on , polished it out with petrol and it worked a charm
I should imagine this took him less than a minute to do....
