painted my 72 this week and noticed the auto primer didnt take the top coat very well :S. theres acouple of runs i didnt even notice !. anyone had a bad day like this? was hoping it would look nice, but yet again doesnt work lol

Runs have nothing to do with the primer, unless the runs are in the primer and you didn't get them sanded out.

Runs are no problem. Give them a few days to harden and file them down. There's a special tool just for this; it's called a painter's nib file, or you can just color sand them out.
