Hay Bob I use it on my 5"x8" coil for the AT Gold. And it work great as I do not have to empty the sand from the coil cover. And it protects just fine. Think if it is used on trucks bed. All the abuse they get and it last.
Just remember that the bed liner spray has to have no metallic particles in it. Just go to any auto supply and ask for a bed liner spray that has no metallic particles in it. The brand I use is Dupli-Color Bed Armor. Just coat the coil at least 3 Times. You should have enough in a can to coat at least 4 coils. When you are finish spraying a coil tip the can upside down and spray till you get no liner spray out. That cleans the nozzel out. Good luck
