When i paint whole cars i borrow a buddies scaffolding, there is no way in heck i can reach the top. But with scaffolding you can go over the top but have to be very careful you dont drop anything or any dust on it which is extremely difficult.....one time i even dropped the dang paint gun right on to the top of the car with wet paint.......aaaaaaggggghhhhhhh Sh$% Sh&%
