.....you obviously paint in the same fashion as me
Before going all out for a complete rub down to bare metal /plastic/resin I will wait for the paint to dry, and while holding the body under slow running water or in a bowl of water, using gentle circular motion, rub with 1500 grit wet or dry paper. Be patient, and gradually the run will sand back. Once level, continue with 2500 and then 3500 grit paper. I tend to give all my paintwork a good going over with 3500 anyway.
The other way is to use Halfords rubbing compound in gentle circular motions. Be VERY gentle. All this takes a while, but can save a whole lot of time and effort masking and re spraying.
I have mostly used the above on cellulose paint, but achieved good results with enamel. (Enamel took a lot more patience as you can easily take off the top coat with the rubbing compound.)
If all goes belly up, you can revert to plan A and re spray!
Good luck!!
