Going with a place like earl will never give you anything near a show quality car. But, Occationally, they can do an 'OKAY' job.
I've had two cars painted at Earl in the past. One I had done 5 years ago came out pretty good (a roadster) and WELL expceeded my expectations. 2 years later I had another car painted at the same location (paid more $$) and the paint and body workwas extremely poor, absolutely aweful.
As other have mentioned, you need to strip everything off your car...every drop of chrome, emblems, grill, taillights Usually Earl does a pretty poor job of masking, a poor job of cleaning overspray. So...for example, if you remove your grill, make sure you put paper in front of the radiator (ie, grill opening), otherwise, they will paint your grill. Anything inside the car you want to protect (ie, dash), mask it off yourself.
Now somewhere in the Valley (maybe Chatsworth?) Earl Schieb's Son runs the local paint location. I saw a Camero article which detailed how to have a classic car painted at Earls (it Featured Earl's Son Location).
Ask the branch manager who is the best body prep person, and ask if they can work on the car. Make sure you find out who is the best painter...have them shoot your car.
Here are some photos of the 65 1500 painted at Earl's 5 years ago. In the pictures (taken by Alvin) it is dirty from sitting in the owner's garage...
