Not even close to enough paint, I don't think I could get that car covered well with a half gallon of Urethane, even though good Urethane will cover like crazy. I imagine I would use about 3 quarts just to cover the outside of a Mustang so to be sure to have enough paint on the car to cut and buff.



Thanks, The DuPont code is Spectramaster Blue BS612FH, I picked it out of a chip book, when doing this there is always some consternation because chips can be deceiving, but I like the way the paint looks on the car too. .

 

We just tuned our gun and sprayed the door and the headlight housings. We didn't realize how poorly tuned our gun was until we played with the volume control today. We were misting it on last time. I also made sure to hold the gun closer to the surface this time.

There are now 4 fresh coats on the door, along with whatever was scuffed up from last time.

 

In addition to what everyone has said, getting the gun setup right is key. You need to measure the air pressure at the tip, barring that makeup a pressure gauge like the one shown below and measure at the gun. You need to set the pressure with the trigger pulled. This will give you a good starting point. If you're measuring at the compressor you're going to be way off (on the low side) which will give you a fair amount of peel.

What gun are you shooting with?

 

We're shooting with a generic gun that we bought for about 90 dollars. Not the best gun in the world, but it covered the car in primer pretty good. It has a gauge at the hose right before it enters the gun, and this gauge drops when the trigger is pulled, giving you the pressure at the tip (we're shooting at about 12 psi at the tip, 20-22 at the inlet).

 

Setting the gun is very important to reduce the time you will spend cutting and buffing out orange peel.
Here is a good write up on how to do it. http://www.hotrodders.com/articles/spraygun.html

I shot 4 coats of clear to give me enough material to cut and not burn through when I painted my 66.

Thanks for the pics and the article chris66dad. I used that article to tune the gun, and shot 3-4 coats on the entire car today. Putting in perspective, before we only used a little more than a quart, this time we used 2 and a half. The paint went on good. There is more of a shine to the car than there was before, and the texture looks smoother. It was almost as if the gun was just puffing it on.

Now we have an even topcoat, but now we have a new problem. On the quarter panels, right around the wheel openings there is some awful looking peel. It almost looks like contaminated paint. I cleaned the car before shooting today, nice and thoroughly, but now we have this random contamination on the left AND right side of the car, in the exact same spot. Can this be wet sanded and buffed? or am I better off wet-600 sanding it and shooting it again?

 

Can you post up some pics?

 

my way has always been the final primer sanding with 400, wash the car with tide and let drip dry completely and sqirt it......i had tryed that oil/grease remover and it always messed up! i color sand with 600,1000,1500,2000 then buff with a wool pad and finalize with the finshing pad...works pretty good.

 

I sanded the bad areas down with 600 and reshot them. The entire car looked good. I went out and bought a good polisher, and began the wetsanding/buffing today. I think I got it down. Thanks for all the help guys.

 

Damn, you're ridiculously talented. How long did it take you to paint all those trees on your hood? :P
