I know how you feel, I am the same way. LOL.

Actually everything comes in a very small box, 2" x 1.5" x 3". Pros do something called wet sanding when the paint or touch up. The grit is very fine and simply smoothes the surface. You can then buff out any fine scratches.

I am going to try a couple small chips inside the door just below the latching loop where I think my seatbelt may have swung back and caused a small chip (invisible with the door closed). Will let you know when I get up the courage...
