worse comes to worst, Battousai, about your case, you could try sanding it down yourself, then respraying it. the red is definitely oversprayed, too many coats, too fast. the blue looks like it bled, leading me to believe it was sprayed too think, and not allowed to fully dry. sounds like a rushed job. not sure if you want to DIY it, but i'll just give you a rough guide since i've NBTD right now

here's what you can do. go get yourself some sandpaper, from 100grit to 800grit. you can also get some 1000 and 1200grit for finishing up later.
wet sand the paint off by getting a small basin, and dipping the affected part in and sanding it while its in the water. you can use some dish washing liquid while wet sanding.
once you've stripped it all off, get yourself some good paint, or if you're a cheapo like me, get some rm5 paint

get a primer, undercoat, and then some white and whatever color you are planning to paint. you might want to get some clearcoat too. apply very very light layers, and let them dry for around 15mins per coat. you should probably check out some modding guides to get a rough idea.
just make sure that you let it dry off in a place with no dust, or not much air, or else it will get stuck in the paint. you can either get a box and put it over your painted materials, or stick it into a cupboard somewhere.
once you get to the colors, put heavier coats on. finally, once you've put your last color coat, leave it to dry for a few days in the cupboard (if you used it earlier). then lightly sand with the higher grits, and apply thick coats of clearcoat, allowing a day or so between coats for it to dry.
without buffing it i doubt it will ever be mirror shiny, but at the very least it will look better that it does now.
