Finally got around to using the Delicate Surface Frog tape today while spraying the first trim color on my Novar. I had done some test panels because I thought it might work good as a fine line tape. Results were good on the test, so I gave it a go on actual job. It worked great as a color seperation fine line tape, with the results as good as any dedicated fine line tape I have ever used ( 3M blue and green, and Finesse Edge)... Only negative is it only works for straight lines, no curves. It is .75" wide, so I stick it down to table top and cut in half to get double the coverage. Has the lowest tack of any tape I've ever used and it comes up real easy, minimizing possible paint pull up. This delicate surface version is yellow versus the regular Frog tape which is green. Lowes and HD didn't have it, I got it from Sherwin Williams, about $6/roll. All the lines in pictures were done with the Frog tape except the Pants and Cockpit. The material was Brodak dope and Finish Pro Slow lacquer thinner.
Also, this tape is very thin (about the same as the 3m green and the Finesse) so it leaves a minimal edge at the color interface. What little edge is left after tape removed was easy to knock off with the credit card trick. I usually wet sand that edge before clear coats, but in this case I think I can skip that step. Will test out that theory on the bottom side first.
