I am getting my windows tinted... What should I look out for too see if its a good job?

tint that goes up to the edge of the window, but not all the way. and also tint that sits below the
 

door line.

what do you mean below the door line? What about the back window..other than one peice?

Go to a place which offers a warranty.

but how do I know they did a good job?

make sure they pull the 3rd brake light and tint over it instead of around it.

Re:around the edges of the rear windshield there are little black dots, >
 

if they do a crapy job youll see alot of air bubls in between them, there will always be some , but some installers dont even try to work them out.

in the back window you only want one peice
 

if you get 3 peices then you can see the lines in the back window, which makes for a bad tint job.

how dark are your windows?

Honestly, this is how I tell a good tint job from a bad one:
 

I use my polarized sunglasses to look at the tint.

On a cheapass car with a cheapass tint, you'll see huge dots, lots of color changes, etc, while a good tint like on a stock BMW or on my car (Ray Ban tint), the window will be almost uniform, almost no dots, or if there are some, they will be smaller, not 1" round thingies.

best of luck
