I'm looking for a means to bond/adhere a sheet of 1/2" thick high density polyehtylene to a steel metal surface. The Poly is glass like smooth and the metal surface is enamel painted. I can remove the paint if necessary and am seeking a non-mechanical means of sticking these to surfaces together. To get a better idea, I have a flat surface metal shop cart that needs a sheet of plastic on the top substrate surface and don't want it sliding off when parts are placed onto it. I really don't want to have to drill and tap from the bottom. Any ideas are greatly appreciated.
