Yeah, point #1 = relax. That one was huge for me. When Phil told me that, it made my learning so much easier. I also was comforted that if I screwed something up (heated up the injector, let the fire go out, etc.) I had a pro to show me how to fix it!
The one problem I found with WD-40 on the paint and bronze of the spot plates was that it looked good still wet, but when it dries it makes the paint look rather dull. The esterline restores the paint's and metal's luster, making it look like new.
I was searching under the wrong first name on FB. See you around the online cosmos...
