Thanks, mates! Tim, you may have noted that even though I thinned my paints for the brown and reddish woodgrains they still came out quite dark and distinct. So, I had to tint my varnish a bit more opaque and lay it on thicker than intended. It still turned out golden yellow, but a bit more intense than I was after. Depending on which of the varnish tones you're after (clear, honey yellow, or red-brown, I'd recommend a test on scrap plastic with the same base coat you intend to use on the model to ensure that you avoid the problem. The masks seem to be fairly resilient and cleaned up very well with just a dip in thinner, so I will certainly use them again on my D-III, but I will definitely test my grain colors before commiting mask to model.
