Go to a local auto-body supply store. Find a friendly one willing to guide you. It's worth it to pay a little more to get the help. This stuff is not cheap. My advice is to stay in a paint "family". If your local guy sells PPG buy all PPG primers, fillers and paint. They are designed to work together. They will have all the bits you haven't thought of like thinners, tack rags and filters.
