I am gutted!, I have stupidly done some black hammerite spraying of parts at the other end of my garage from where my fairly newly painted mini is situated and a thin film of the paint has covered it. It must have been in the air and settled onto the paint work.....

In the panic of realising what had happened I have washed and polished the bonnet to see how easily it comes off. With lots of polish and painstaking rubbing it does come off, thank god.
My questions are threefold,
1) should I keep polishing the entire car until sunrise before the Hammerite cures fully, or can I takle it over a number of days???
2) Is using polish the best way to remove the thin film from my paintwork?
3) Is there a rubbing compound suitable for the job?? My paintwork is a waterbased paint with a laquer finish. Will the hammerite react with the laquer??
All help appreciated, Please.......................
