its not a pain in the ass at all....prepping is really easy but just needs to be done right and taking your time. Im a car painter.....anything you want to know...... just give me details. Most of the things 5th gen stated is incorrect anyway. (especially the part about touching it with your hands. OIL causes fish eye and it usually accures on your clear coat and not your base.(although you do have oil in your skin) unless someone just takes their finger and intentially rubs it all over the base coat, thats the only time i see it happening)
