Difference between show car and dailey driver

looks like it has a tad bit of urethane wave. Nothing too bad. Other than that it's pretty damn slick.

I've never had a problem with "urethane wave" so I can't comment on how to remove it. What I see in the above pictures is the edge of the lamps and the edge of the roof in the bottom shot. They are not smooth like they should be if sanded and polished to the max... ie. "show quality".

Man, I always get jealous of the guys who never have this problem I know a couple painters who say they have never had it happen, and sure enough their paint jobs come out glass slick. Must be a gun setup or spray technique thing. But yeah I see the pics you are talking about with the op, and it's pretty difficult to see uro wave in any pictures so it could just be my eyes. It's not any major uro wave at all that I see, it just seems that he could've sanded with a harder block and courser paper for it to come out "show quality". A lot of the urethane wave I see can make a brand new oem panel look like a sack of rocks. It's been discussed here before I'm sure, and on other forums as well. There's more guys out there that could give more accurate detail on the uro wave subject than I can.

"Urethane wave" is directly related to how much clear is applied. It can be reduced by CUTTING the clear flat using a block and 600 or so paper after a few coats and prior to applying more.

I have came to the conclusion if fewer coats is applied, you have less. If you apply a couple of coats and sand and buff you are going to have a much nicer finish than if you apply three or four "just to be safe" and cut and buff.

I have measured with a digital mil guage and a nice cut and buff cuts about a half a mil off. So if you have applied the two med wet coats as recommended in the tech sheet of most any high solids clear, you have the 3 or so mils and then cut and buffed end up with the 2-2.5 you need for protection.

I can name a shop that specializes in applying urethane wave. Comes supersized with every 10,ooo dollar paint job. :mad:
Okay, I'm grumpy.
