talking about spraying semis i was painting for about 8 years at a shop and decided to make more money at a truck body shop. they made me walk the mast of a bentley roll off trailer while it was 1/2 way up when i was walking down i had to spray it and get ever nook and cranny. this was on my first day people in the shop was taking bets who long i would last. they said car painters never last. i got in the bet and won because i left that day. commercial equipment painters have it rough and i found out in my area they dont get paid like a car painter.
