I want to paint my beater K5 in a flat desert sand color. I don't have any hard top, doors or tailgate on it. How many cans do you think I will need. Also, I am not going to fix any bodydamage that I have, I just want to scuff the paint and wipe it down with thinner and then spray it. Does anybody have any suggestions on how to do this easiest, the cheapest and fastest way. Also, what is a good brand spary paint?
