I got one thin layer on, and think I'll do another coat, but it's calling for rain again, so the second layer will have to wait. These tarps work so great with my son and I hanging under one, that I'd like to get it to work. With two layers of the sil mixture on, it'll only cost me about $4 and a little bit of time. I honestly think the very light layer of PU just wore off from under it. It was very thin, and it's like you can't feel that layer anymore.

This was all in hopes of rinsing off whatever PU coating may still be around. I don't know if it made a difference with the sil mixture soaking in, but those are the steps that I took, and it appears the sil mixture soaked in quite well by using a 3" foam brush and sort of rubbing it in. I did a thin 4:1 mixture (by weight), mixing by putting in a water bottle with some pennies and shaking the heck out of it.
