67/68/69 cuda dilemma

I painted my Dart with bc/cc and my Belvedere. I'm not impressed with the durability. I sure didn't like all the sanding steps involved with bc/cc finishes. I painted my CJ-7 with single stage and it was really durable. Just a little color sanding and buffed.
Maybe It's just the black color on the Belvedere but it seems to scratch just looking at it. I haven't noticed any scratching on the Dart. But it's white.
I probably did something wrong when spraying the clear.
Mind you I'm not a professional painter. Far from it!!!!
