My theory is that paint shops cheapskate on the paint and use fewer layers that the manufacturers. Also, you can add hardener to the top layer to prelong the surface - as a cost saving device some paint shops may not do this. Combine these and you get thin, weak paint.
I'm presently teaching myself to paint for when my race glass turns up. I'm using more layers, hardener in the top two coats and then a clear layer. Hopefully if I drop it at the track it will just bounce

Lots of clear coat Mike. Even with small chips/scratches most will polish out. Also the paint looks awsome, realy deep(just make sure it has cured eg. oven. Corvette at Summernts in glitter had 26 layers of clear(just to get a level surface). Problem was it was 18mths old and still hadn't fully cured.
As for the hardest paint, that winner is 2 pak, problem it 2 pak is a pain in the ass to use. I have done 2 pak at home in the garage but the over spray sticks to anything and everything. The worst part is it does not cure like acrylic, it will go tacky and this includes anything it comes in contact with.
2 pac tends to be a pain to touch up. But also looks great out of the gun without the rub back/cut/polish.
