Learning to paint....

I've got a Devillbis Tekna Pro Lite, and use it for both base and clear. I clean it brain surgery clean after base coat, and have had no problems. I use the 1.4 tip for both. When I did the Leer fiberglass topper for my wife's Dakota, I used it for sealer, base, and clear. I did about as much gun cleaning as I did painting....lol.
