I've heard of people adding dots or stripes of silicone to reduce the chance of mats slipping on the tent floor. What's the best stuff to use? Silnet or just blobs of bathroom sealant? Neat or thinned down? Dots or stripes? Floor or mat? Silicone tape off ebay? I need to do both silnyon and Cuben if I'm doing the floors. What worked for you and what did not? Alternatively, I'm considering making a "slip" / partial mattress cover. About 2' long made with a Merino (or lycra)) top for comfort and Tyvek or Cuben base i could add the silicone dots to. Seems a feasible little project that i can transfer between mats and shelters. Your thoughts?
