there was a thread about the bedliner "treatment" not too long ago.

if you don't really feel like reading through all 8 posts on there, here was my 2 cents about using it on the coil:
"very easy, simple and quick! and seems to be extremely durable!
just clean your coil thoroughly and make sure it's dry. spray on an even coat of the bedliner, wait 5 minutes and give it another coat and within a very short period of time (20-30 minutes) you're good to go!
the liner is similar to a thick paint, will dry with a bit of a rough surface not smooth like paint and dries DRY, not gooey or even rubbery. 2 coats are roughly 8-10 mils thick so there'll be very little if any difference with detector depth issues and unless you look closely, you or your hunting buddy won't even know it's there!
it's not meant to prevent major damage to your coil from a hard hit to a rock, but will help greatly with those little bumps and scrapes. besides spraying the bottom of mine, i've also given the sides the same 2 coats just for a little bit of added protection there too. we all bump things, so it's better safe than sorry.
the brand i used is called "EZ Liner" and the one can would likely be enough to do 20+ coils!
so yeah, that's about it: clean, spray, wait 5min, spray again, dry for 20, swing!"
i didn't bother with any photos since applying it is just like giving anything a coat of spray paint and when it's done and dry, you can't even tell that it there! a photo of the finished coil still looks just like a coil.
that brand name i listed is about $10 for a can.
