49WillysSD... Prep the car and get it ALL ready. Cover the interior, engine bay, etc. Spray the basecoat in the doorjambs, hood jamb, inside the gas filler door, etc. Next spray on the color coat and follow that with a thin coat of clear to stabilize the color. Let it dry for a couple of days and assemble the car. Now comes the fun...

Mask the doorjambs, hood jamb, and everything else that you already painted and don't want oversprayed. I do this with lots of 2" masking tape. The jambs have to be 100% covered so that NO overspray can get to them. Now, with the car all assembled and closed up, sand off all the overspray around the door openings, hood seams, fender seams, gas filler door, etc. Now apply your basecoat to the entire exterior. If you find any problems with your prep work or flaws in the bodywork, fix them now and recoat with the basecoat. If you have any spots where you have to remove dirt particles or bugs, etc. you will have to reapply basecoat. After the candy color has been applied it will magnify any flaws and candy colors can not be repaired or spotted in.

If you are happy with everything so far, after applying the basecoat, do not touch the basecoated surface with anything but a tack cloth. Sandpaper or scotchbrite scratches will show through the color and will actually be magnified. If you are satisfied so far apply your candy topcoat. The trick here is to apply it evenly and avoid overspraying any "dry"areas. For example, you cannot spray the fender, then the door, then the rear quarter, etc. because every place you overlap your spray pattern the color will go dark. You have to start at one end of the vehicle and walk the spraygun all the way to the other. Then go back the other way, again the full length of the vehicle. You will find, on a sedan-delivery, that the roof will be the most difficult part. Your spray pattern has to run the full length of the roof - hard to do if you're standing on a stepladder...

You say you have experienced help? One of the best ways to do a job like this is to get two painters with similar or identical spray guns. Load 'em both up (the guns, not the painters) and both painters start spraying at the bottom on opposite sides and meet in the center of the roof. This keeps the entire vehicle wet for each coat. Have the painters switch sides on alternate coats so that both sides get the same amount of paint (no two painters shoot exactly the same).

Finally, apply the clear, all but the very last coat. As soon as possible, carefully open the doors, hood etc. and remove all the masking. Now shoot he final coat of clear finishing up by opening the doors, hood, etc. and giving those areas one last shot while the outside is wet and all will flow together.

Good luck. I had been painting for about ten years befor I attempted an all-over candy job...
