For those that want to save by doing it themselves:
Please, Please read all you can about how to protect yourself from paint chemicals, especially hardeners. Read the MDS for every product you use. You can do some serious, permanent damage to your lungs, liver, kidneys, brain, etc... by not using the proper safety equipment.
It is important that you take the time and read ALL you can and make an informed decision on your own.
I have started to get into this "painting" thing on my own, no mentor. There is a local paint jobber staffed by knowledgable and helpful 20-30yr veterans, but half of them look like they're strung out on meth. I mean they look rough. After seeing them and what this stuff has done to their health and appearance, I have decided that I will just do the dents, dings, and primer and pay a professional to take the risk with the finish coats.
From what I have found, the dangers are greater for the do-it-yourselfer. We are less likely to have the proper ventilation, which is the key to protecting yourself.
Go in with your eyes open, and know the risks as well as the rewards.
