rickm, you are also gonna need a needletip applicator bottle to put on the #3 with....it is the only thing that I have found will work well. They seem to be hard to find, but US plastics has them they are just hidden really well on their web site! The us plastics part number for these bottles is 37524 and they cost around 2 bucks each. they call them a plasticator bottle. Shawn
