OK, I know what you are saying, but I think I will go with my original plan. I'll have a slight line about 3/8" in. Paint will get in that far without opening door. I'd rather that so I can focus on doing the outside. If I start opening and closing doors, I am asking for disaster. Should be close match, I painted the jambs last year.
What do you think of Ray's idea to just let the overspray hit it -no tape?
