Well, I used the kit masks for this kit but for the most part I use Tamiya masking tape cut to the contours of the canopy. Now, for some reason....I have not been very successful in preventing bleeding in some places, for this kit it was minor and mainly a little on the upper portion of the sliding canopy. I will take a better photo of the canopy for reference. There are some other issues with masks that I have had with masks and will probably start another thread on that.
