Yea the door jam stuff I found on YouTube isn't good. Try searching How to Back Mask Base / Clear by jimmo4life May 14,2012. Pretty good instruction, can't say the painters technique is very good but covers the back masking and even spraying blender.
I like to peel back the back masked tape with each pass of base and clear. It just softens the line for less blending when done.
Now keep in mind originally we were talking about a buff thru on a door handle. Concepts are the same it's just a much smaller repair. When learning the rotary I caught a hood edge on my white Explorer and burned thought the clear and base coat. Being a white car only a few years old it fixed right up and you couldn't even tell. I'd much rather have a door handle blemish cause everyone always looks at the hood never at a door handle!
Let me know if this helps. I don't have anything set up to paint right now but the next time I break out the airbrush I'll take pics and/or video for posting here. I could set up a sheet metal panel and demo this for you this weekend if you need more info on this technique.
