what causes single stage paint to orange peel?

just the nature of the beast .....it dries so fast it doesnt flow-out , an ya get orange peel

thank you, i won't put it in the sun right away this time,,,

Actually orange peel comes from the way that the material is applied,not the material make up or type of paint.granted some spray better than others but lets get to the point.usally peel is achieved from being to far away from the panel or to high of air presure ,or a little of both.if it is drying to fast try a slower reducer and hardner this will give you a longer window and it will flow out some more for a smoother look.

Bent got it- base/clear can do it too.

Reducing the material incorrectly is probably
the error most make that have that problem.

not mixed right or to cold or wrong air pressure the smother you can get that paint to lay down the better sometimes its how thick your applying it watch what its doing as you laying it down

It's also why two stage is so popular. The color coat is relatively easy to apply. Multiple coats of clear can then be color sanded flat and polished up to a high shine. Single stage paints must be applied just so and when done correctly, look terrific. Knowing how to push on alot of paint and not have it sag is a skill that requires alot of practice. Air pressure, gun adjustment, distance from the work, keeping the gun at 90 degrees to the surface and speed you make your pass all go into the equation. I've seen skilled painters put on a coat, leave the booth for a few, come back, put on another coat, leave the booth, come back in half an hour a see the paint has flowed out beautifully.

Actually orange peel is caused by an inaccurate fluid adjustment. Too high an air pressure causes runs and sags.

The best way to reduce the affects of orange peels is to increase fluid flow and adding a slower reducer. More paint flows better than too little paint. A slower evaporating reducer allows the paint to flow before becoming too thick by the evaporations of the reducer.

Even the clear coat of a bc/cc system will orange peel if the gun adjustments aren't correct. It's just easier to sand out the imperfections, then buff and polish than it is with a single stage paint.
