I also sprayed some blue on a piece of plywood. There are probably about 5 or 6 coats on this... (the plywood was cold... pun intended).
Anyhow, after it cured several days, I wanted to see how it stuck to the plywood, and I must say, it was stuck pretty well. It took a lot of effort to pull it off.
Here is step one....
As you can see in the second pic, it stretched quite a bit and not a huge amount had been pulled away from the plywood at this point.
Yeah, it was stuck very well.
Yeah, somewhere along the line, I think I see some of this in my future, although not necessarily blue! Wahoo!
