how many coats in one day?

[58mark]

I'm renting a compressor for the weekend I paint my car. I'm going to do base in the morning and the clear in the afternoon. (i'm using universal clear)

If I'm not going to be able to spray three coats, cut and buff, and then spray three more coats, but I was hoping to spray at least 4 coats, cut them a week later, and then buff

I know the "perfect paint" write up says 4 is ok, but is there an advantage to 5? If I was going to stretch it to 5, should I wait longer that 20 minutes between each coat to clear more solvents?

another option is to do 2 (or 3) coats in one day, and then come back the next morning and do 2 more. Should I light sand before I come back the next morning?

thanks

Four is best with 30 minutes between coats, more you risk solvent cloudiness unless after four coats, up the flash to 60 minutes. Still to risky in my book to do more then four.

ok, thanks. I knew there was a maximum, I just wanted to hedge my bets against going through the clear with cutting. Newbia paranoia

Is there any advantage to waiting 60 minutes flash time if i'm doing 4 coats?

60 minutes won't hurt, and really see no advantage as long as spraying temp is 70 or higher. Dust would be the issue.
