This happened to me too. I'm told giving it a brush-over with even a Scotch-Brite pad should do the trick. Just don't dig in too deep. Your prepping the surface with a little scoring, not trying to work down through the layers.
I've also used spray paint for plastics. I used Valspar black gloss twice. I don't know if Krylon would be a bit stronger.
One other thing you need is PATIENCE!
Give each layer at least a day to fully dry, and try to do it where you don't have to worry about dust/particulate getting into the paint. Once the first layer is dry, give the surface a very light once-over with the scouring pad or fine sandpaper…something to give the second layer to hold onto. Then go over the finished (and fully dried) layer with layers of clear coat, gloss or satin…whichever you prefer. Do at least three coats a day apart, just to be safe.
I know some may say a day between coats is taking too long, but if the paint doesn't fully dry, you'll get a blistering effect where your thumb makes the most contact. (I once tried adding a new layer of paint later on, and the lower layers didn't meld well and I got an unintentional crackle effect) So, I say let it dry fully. All it costs you is some time and patience, because if it doesn't take properly, you can't just hit "RESET" and start over.
