Is there a way to even out uneven parts of a paintjob, such as areas where paint has flowed and accumulated as it dried? Or do you have no choice but to strip and start over?

you could try sanding the area with 800 to 1000 grit wet and dry sand paper. Then overspray again.

I agree with Mr Roo...g'day mate...
I do the same: you could also try a couple of drops of Fairey Liquid or other dish cleaning liquid in the water when you wet sand. I find it helps to lubricate the job and helps the wet and dry paper glide over the surface...using very light pressure.
Hope it helps

Here's an alternative solution if you're afraid of sanding off the details: use acetone to remove the paint and simply repaint that section again.

I recommend you get the moisturizing acetone (it does not dry quickly). You can go to any Hortaleza beauty care store to buy 'em. The cheapest bottle costs less than 30 bucks.

The acetone will also melt the plastic! A bit too risky for me.
If its just in one or two spots try Mr. Muscle oven cleaner from the spray can. spray on area and leave overnight. Rub off with an old toothbrush and water the next day. It will lift the paint but not harm the plastic!
For better contol mix some caustic soda with water and brush on the effected areas. Leave for a while and hopefully the dried paint will lift off! If the diluted concentration is too strong it can warp the plastic... so add carefully.
I have stripped a few vehicles with caustic soda diluted with water before and it works well.

Remember all these chemicals are dangerous .... take care and read instructions carefully! Ask for advice if you´re not sure!

Hi there

I'd try polishing cloths... a bit finer grade than Mr Roo suggests - but the Aussies always call us Poms a bunch of wussers!

I did a thread a while back which might help:

Hi, Blank. When your paint is dried-up, there's no other solution then sanding; but when the paint is still fluid, I allways use the corner-point of a tissue to remove the access paint.

Hope it helps, John.
