I was wondering if its possible to lay down a really nice glossy clearcoat with minimal orange peel that doesnt need wetsanding.
i managed to get oem like finish on small panels using the HF hvlp touchup gun but i havent tried the big hvlp gun yet.

 

OEM finishes are full of orange peel, so you can totally get it to look like that. Is it possibly? Probably. Likely? Doubt it. Wet sanding it isn't difficult, just tedious.

 

It is possible you just have to make sure the booth is free of any particles along with no outside moisture. Then you have to get your psi set up right to match your gun and make sure its a good brand. Then its all on you how experienced you at painting cars and not getting to far away or to close to cause paint runs.
