When you use decals, you can see the model gradually, slowly evolving - hopefully into what you'd envisaged - as you work. The gratifying thing about using the masks is that it's a bit quicker: you add lots of masking and do a bit of painting, and nothing seems to happen
Then suddenly, seemingly in an instant, the masks come off, et voila!
OK, the walkway lines are a little uneven in width, but I can live with that. What I can't live with (although I did seriously consider it) is that the starboard "S" is noticeably above where it should be. I've no idea how that happened, I blame the bench gremlins. Now I'm particularly glad I included a spare on the mask sheet. So not 10 minutes after the big reveal, it was out with a fine sanding stick, off with the "S", and a quick touch-up of the silver; the new S goes on next session when the touch-up's cured.
