I also tried it with the same poor results. Do not waste $20.Don't buy it! I did and it sucks. It doesn't work as advertised. It works on some surfaces for a minute and then the outer later starts to break down. It is not practical since it wears away by touching or exposure to other substances. Also, soap completely breaks it down and washes it away. I wonder if the stuff made at the company works better and maybe the spray can version by Rustoleum is just not as good.
