@@Jonathonconroy Worked quite well, I rolled some blue tac about the same amount of time as I did for this stuff and it can’t go too thin or at least the blue tack I used or tried. This stuff is great for use on smaller minis, 15mm etc. I think the blue tac is ok for say a tank or larger item. If you want very fine mask and I assume a lighter spray with an airbrush this is the way to go. I used cheaper brand of blue spray paint over Army painter grey primer and had nice lines when the mask came off..
