Yeah, that’s pretty good for older silnylon that is starting to mist/leak. If it is stretched, badly 20:1 is more like it. For spinnaker, about 20:1 is good, it stretches pretty easily, often without being apparent, except
from inside against a bright sky. Two coats will often do plain old nylon cloth. I got a bunch here a while ago that was mostly uncoated seconds. It needed treatment. For seams, about 5-10:1 is good. I often do both sides, though. A thin coat does not suffer
from peeling like a thick coat does.
I brush it on an area, working it in pretty well, then move any excess out to the next area. I adjust as I go. The stuff is very watery and requires a lot of mixing, even while working with it. I slob it on and work it
in firmly and quickly, nothing gentle about it. I get a few brush marks, but only a few after it dries. It only adds an ounce and a half to a 9’x9’ tarp or around .1-.2oz per yard. I am still using my 9 year old 9x12 tarp that was cut down to a shaped shelter
and recoated this way. I tried WG, but it evaporates too quickly causing the brush to “stick.”
My thoughts only . . .
