If your talking about 2 stage paint ( base coat clear coat)It's a chemical that's added to the paint so when you do a repair it will match the factory paint orange peel. You can wet sand it and polish it and make it smooth as glass. The only way to get around it is a real slow hardener and hose the clear on pretty heavy on each coat. Allow plenty of time between coats so you don't get too many runs but hosing it on you will most likely get some.

So if its a chemical added to the paint to match factory paint jobs why do factory paint jobs have orange peel ?

It's not a product you can buy !!! The P-A-I-N-T M-A-N-U-F-A-C-T-U-R-E-R puts it in the P-A-I-N-T when the paint is made.
Factory vehicle paint has orange peel in it because the vehicle manufacturer either dips the car body in paint or sprays it quickly then forces it to dry fast by baking it. Either way the paint doesn't have time to flow out or lay flat so it has orange peel.
You can make orange peel less noticeable by putting more material on with each coat, over reducing, using slower hardener for the temp that your spraying in, slamming the paint droplets onto the surface by using more air pressure when spraying, but the only way to get completely rid of it is to wet sand it flat and polish it. Wet sanding is the final process of any quality or showcar paint job like ones found on a Bently, Ferrari, Jaguar, Foose, Codington etc. Call your paint rep or go take classes on how to paint they teach you things like this.
Or take some of the advice here and hang voodoo dolls in your paint booth or use a garden hose to spray it on or turn 3 times to the left the twice to the right then jump up and down 4 times before each coat
It looks like we did a fine job of chasing the OP away and probably left him more confused than when he asked the simple question.. WOOHOO strike one up for the MIDOL militia.

WOW That's great now finish it and win enough trophy's with it to get a Magazine interested in it so they want to run a 5 page article on it. Then I can show you my 92 Vette that was in Corvette Enthusiast Magazine in July of 2005. Then My 80 Vette then my current project my 73 Roadrunner or the 70 AAR Cuda show car I did for a friend. Don't show an UN-FINISHED car and try to make people think you know what your doing or your response has Value. Stop complaining about other peoples responses and go finish your car !!!!!

OOOOHHHHH.... big tough guy!!!
My hot rod got a 5 page spread and mention on the cover in Popular Hot Rodding. Mopar Muscle Magazine did a few pages on the car too. Again, it got a mention on the cover and a couple inches of the editor's page. It was used as a background car in a rock video and in the TLC show Rides.

Did I mention the car has partches of missing paint, holes where the trim was removed, and a beat up hood?
It doesn't take superfine paint to get into a magazine.
