I've also used just the shoebox top. My friend suggested a lamp shade, I guess you can see inside that way.
the shoebox approach is Good for doing a quick coat once a month.
Taping up the car with newspaper is indeed a pain. I had to do that recently to take care of some curb rash. When I was ready to paint the wheels with Wurth, the paint wouldn't come out of the can! ARGHHH. Had to untape the car.

p.s.
I even sprayed my cloth softop cover with Raggtopp.
