i painted my plastic panels yesterday evening, hoping they would dry overnight. well the next morning my mom tells me that she accidentally knocked some panels onto the floor!!! anyways the paint job looks great, but in some parts you can tell some uneven areas, some marks, and a whole bunch of other stuff. so should i let the stuff settle in for a while then repaint it? and when i do repaint it, how can i get to be smooth once again and get all the gunk out?

If you are using plastic and are painting it anyways, I recommend you get a bunch of paint thinner and get as much of it off as you can (you can probably get it all off with a little effort, especially if it is not completely dry yet). Make sure you rinse the surface afterwards with water and let it dry. Then simply repaint it and forbid your mother from going anywhere near it.

Well i would sand the bad spots, to get it smoth, and sand the rest of the paint, not completly off, then give it 2 layers of paint, let it dry and presto!

That means you "can" touch the paint, gently, but I wouldn't. That 5 - 7 days they are talking about is the curing time. While the paint might be dry to the touch on the surface, it is still wet under the surface. If you press hard onto a painted surface that has not properly cured, you can leave permanent finger prints or smudges in the paint. I would just let it completely cure, wet sand the bad areas with 150 or 200 grit, and repaint it. The most important thing to remember when spray painting, is that you do it in several light coats. Also lightly sand between coats using 600 or 800 grit wet/dry sandpaper to help the next layer of paint adhere to the surface. Lighter coats of spray paint can also cure faster than heavier coats.

I totally disagree. I've been using paint thinner on plastic model airplanes for literally years without ever warping the plastic whatsoever. I've taken off entire paint jobs (several coats airbrushed) when I did not like the outcome using paint thinner. It depends on the amount you use and how careful you are. I would think sandpaper runs a higher risk of marring the surface.
