If you are going to paint and run air tools there are at least two sanders you will need. A dual action and a random orbit palm sander. Here is a link to eastwood sanders. Take a look at the cfm a tool needs. You need more compressor than that number. I use at least 50% for head room so the compressor is not running all the time to keep up. So if a tool needs 7 cfm at 90 psi then 7X1.5=10.5. So when shopping thats the minimum I would look for. The bigger you can go the better. The less the compressor runs to keep up the less heat and water you make. That is heat and water you need to have a way to get rid of when it leaves the compressor.
