The Product worked first time, it did not smudge when I put them in place, even when I rubbed a duster over them. I had the clear acetate type, ready to peel and stick, these worked first time as well. The only thing that was a little disappointing was when I applied the finish lacquer, there seemed to be greasy spots where the lacquer did not want to amalgamate into one smooth coat. I used Spray-fix, I do not know if this really suits this product, but I have a full tin of it; so buying another seemed a waste. I would buy this acetate again, just need to find out why the finish lacquer is not right.
