McNett Tent Sure

I'd never used this stuff before. Coverage was not as good as expected, and I need a second can. Seems I bought the last in the country, and McNett no longer makes it. Perhaps that is a good thing, because it is horrible to apply: dries really quickly and will not tolerate overlapping brushstrokes. I ended up with bobbly bits and white streaks. Keeping treated surfaces apart while it dries for 24hrs is almost impossible outdoors in the UK given a groundsheet too large to spread out indoors.
