Reminds me when I did a car spraying course at Plymouth uni.
You could get your car valeted for £5 and a full respray for £50.
It went towards marks for the course and they would just charge for materials.
That being said,two of the young lads decided on a pub lunch followed by numerous joints.They were asked to spray a realitives of the teachers car.
They did it last thing,and the following morning produced much laughter as there were runs everywhere on it.
Teacher went nuts and they had to resand the whole car.
