i'm looking for way to permanently mount ez track.
I used nails thru the little holes in the ties. You can find the proper nails at your local hobby store. Others have used caulking and other methods. Do a search.
After you nail it down, you can cover up the fake beding with ground cover, or sray paint it to your liking.
What material are you mounting the track on? Hot glue can also be used on some materials.
Hot glue sounds like a good idea in principal, but it really is not a good way to go. The problem with it is that both it looks messy, and after a relatively short period of time tend to lose all adhesion with any material, small tin tack etc. are the way to go.
