You are welcome! Hairspray or a fixitive spray could do the trick. Paint is my thing, so your article was very interesting to me! I am also an artist, but a trade qualified painter as well. I also did 7 years in the technical side of paint when I managed a paint shop!
Your article also made me remember when I was a kid, I was desperate to have a tan, and I used to paint my legs in coffee ! They too went sticky! Ha ha!!
