Okay! So I need a bottle of MicroSol and a bottle of MicroSet? Thank God for this forum. I like to get all my ducks in a row... Before I shoot them. MicroSol goes on the already finished metal, then the decal goes on and then MicroSet goes on. Correct?
Sorry, I had it backwards. Microset first (blue), then decal, then Microsol (red). You may not need the Microsol; it's most useful for getting the decal to snuggle down over protrusions, but your dial looks like it will be a smooth surface once you've cleaned it up. If you do get any air bubbles under the decal despite using Microset, you can pop them with a needle after the decal is dry and then flood the area with Microsol.
It doesn't look like it in the posted pics but does this coating leave a visible layer that is obvious?
No, no visible coating other than the decal film, which you'd get even without the decal setting solutions. You'll probably want to clear-coat the dial after applying the decal to help hide the decal film.
