Step by step clear coating help.

Can someone out there who actually knows how to apply clear coat properly help me out with a brief step by step how to?
 
My questions are
 
How many coats?

 
Do I sand between coats?
 
Should I use an orbital buffer after it dries?

...if so...

What kind of pad on the buffer?
 
What kind of rubbing/polishing compound for the buffer?

 
I know its a few questions, but thanks for your help.

this is how i do collision painting   let the base dry for 20 30 minutes then mix up clear put i good med wet coat on depending on how much there is to paint i will do wet on wet so as soon as im done with the first coat i start the second coat and put on a good wet coat then bake it for 40 minutes at 140 (thats as high as our both will go) then let it sit till the morning and wet sand it and buff the dirt  out i dont sand the whole panel cuz there is no need for it i found its easier to lay your clear out nice than it is to cut and buff every panel and i would not use a orbital buffer those are junk i use a dewalt 8 inch buffer with a white foam pad for the compound then a grey foam pad with glaze and a blue foam pad with the final blue glaze and i use all 3m compounds   now on custom finishes or show cars i will put my clear on wet on dry put a coat on then wait till its finger slick and i will put up to four coats on so i have plenty to cut and buff or plenty to block with 600 and clear again to help eliminate the urethane wave then buff the same   hope that helps some and this is just my way im sure every painter has his own technique he likes this is how i do collision painting   let the base dry for 20 30 minutes then mix up clear put i good med wet coat on depending on how much there is to paint i will do wet on wet so as soon as im done with the first coat i start the second coat and put on a good wet coat then bake it for 40 minutes at 140 (thats as high as our both will go) then let it sit till the morning and wet sand it and buff the dirt  out i dont sand the whole panel cuz there is no need for it i found its easier to lay your clear out nice than it is to cut and buff every panel and i would not use a orbital buffer those are junk i use a dewalt 8 inch buffer with a white foam pad for the compound then a grey foam pad with glaze and a blue foam pad with the final blue glaze and i use all 3m compounds   now on custom finishes or show cars i will put my clear on wet on dry put a coat on then wait till its finger slick and i will put up to four coats on so i have plenty to cut and buff or plenty to block with 600 and clear again to help eliminate the urethane wave then buff the same   hope that helps some and this is just my way im sure every painter has his own technique he likes
