I did something stupid, well I hope it can be fixed. I had areas of my bumper where it is exposed to the plastic, so I got white touchup paint (dealer brand) and filled them in.

The next day after it dried I used 2000 grit sandpaper and wetsanded the areas to smooth the paint out. OK it looks a lot better... the problem is that now the touched up areas around it is really white. What do I do to make it match the paint? Do I have to use clearcoat spray? Buffer???
