First question what do you plan on painting? That is the first thing that you need to answer. Half my struggle when I first started ABing was paint so I am gonna help you out. Decide this and base your paint decision off this. You are going to want to after this learn to use a perticular paint system. By doing this it will take away a huge headache when working. You will know how much to reduce or how much trans base to use to get your effects. There are a llot of multi use systems out there now such as etac and wicked paints. I have used etac, wicked, goldens, HOK, Autoair, createx, and even the cheapie bottles from walmarts. Just remember knowing a paint system will help with consistancy. After you have learned a system and feel comfortable expand see if you like some other products. The knowlegde you learned from that system will help you down the road.
