Can you only color sand single stage paints? I had bc/cc sprayed and theres a hell of alot of orange peel, other than that it isnt too bad. Color came out strange too, it will have to grow on me. Not sure if it was the guy who sprayed it, or all my prep work and primer. Either way is cool, doesnt bother me. I'll have pictures very shortly

You can sand it but you have to be careful. You don't want to sand through the clear, so I hope there's plenty of clear on there. Some other folks might want to speak up, but I think that your best bet for getting rid of much of the orange peel is to start with a fairly rough grit. If you start with a real fine grit, I think it rides up and down the orange peel and doesn't get it out as well. Just don' break through the clear into the color.

There is 3 coats, a fairly good ammount of clear on there.

Also, Im very curious to know what the cause of orange peel is?

Yep, spray technique(gun pressure and flash time) is the most common cause. Ive wasted alot of good clear till i figured it out. Airflow in the booth is a big cause, its very important.
Also IMO 3 coats is the minimum to cut/buff, so be careful sanding /buffing esp at corners.
Post up some pics, we'd like to see them.

Thanks guys, I'll have pictures up today. Theres enough clear left for 1 or 2 more coats if needed.

You need to be careful with only 3 coats.
4-5 would be much better.
Let it cure for at least 3 days.
Start with 600 or 800. Do not allow it to
load up on the paper. Do that by keeping water
on the surface. Watch closely for the little "diamonds" of orange peel to go away.
Block in a straight line with a rubber pad or backing. After you have the orange peel
sanded off, go to 1000 then 1500.
Buff with a foam pad with 3M liquid buffing compound. Start with Medium cut and go to Fine and finally the swirl remover.

Orange peel is caused by poor atomizatioin of materal out of the gun. In other words, low air, or too much paint, etc.

not an expert, but, been there, did it to me.

good luck

Instead of praying you don't break through the clear, knock down the orange peel with 600 grit, but be conservative. Don't try to get it all out. Then put on a couple more coats of clear (hopefully with better technique).
That link above isn't all that helpful. "Either you are too close or too far away. Or your spraying too much material or too little." There's no substitute for experience I guess.
I've done a little reading about orange peel myself. (Hotrodders.com is pretty good). Someone suggested turning up the air pressure for better atomization. Just out of curiosity, what ype of gun and paint did you use and what pressure were you spraying at?

Just got done color sanding the 70 a few weeks ago. Had about 15 hours of sanding into it alone...not including the buffing, polishing, etc. My orange peel was not all that bad, so I started out with 1500 grit 3M paper and used a spray bottle in adition to a bucket to keep everything nice and wet. Put some soap in the water too...makes everything go much easier.

You really need to get the surface as smooth as possible with no traces of the orange peel left otherwise all those small imperfections will be magnified once its buffed out.
