In addition to the other suggestions you've received on this issue, if you want to try to fix it yourself, you could do the following...
make sure that the touch up paint that you have applied is *above* the surface of the original paint. If not, put some more on. Get to a real auto paint supply and get yourself a "nib file" or "run razor" or similar device, an assortment of fine (1000-2000) grit sandpaper, a good power buffer and lambswool pad, and some polishing compound. Explain to the counter guy what you're trying to do, he will likely be able to offer recommendations on specific products to use. Carefully bring the level of the touch up paint down to the level of the surrounding paint with the nib file, taking care not to actually cut into the original paint. Then wash the panel THOROUGHLY with dish soap and warm water, rinse, and wet sand the panel lightly with fine grit sandpaper - nothing you'll find at your local hardware store, start with 1000 or 1500, work up to 2000. Don't try to take a whole lot of paint off, you're just gently smoothing the surface. Then buff with polishing compound on a lambswool pad, wash again with your dish soap, and apply two or three coats of good wax.
enjoy!
