A 2hp compressor is a little small for what your doing, unless you do a panal at a time. I use a 7hp compressor, and I've done my jobs at home. Color will be a factor. Single stage colors are easy, 2 stage colors (basecoat/clearcoat, metallics, pearl base and candy based) are more time consumming. I would spend sometime with someone who paints, or watch a car getting painted before you try to take on the job yourself. Remember, 90% of the job is in the prep. You can spend hundreds, if not thousands of dollars in matierial, to just have it wasted on a poor prep job. The actual painting is relatively easy. I've been an automotive painter for 35 years, painted the most basic colors to multi color flames, faded multi color stripes, and every imaginal color scheme, and the biggest lesson I've learned is being patient. Good luck on your first paint job.
