Second to none
This stuff is great. It's ridiculously expensive, as are the hoses for them, but it's second to none in cavity wax. It goes a long way as well. One of my cans arrived damaged, but after providing a photo it was promptly refunded, no harm no foul.

Awesome stuff, not just for cavities either.
Sprays thin and works into crevices, sets up to a nice wax that does not harden or flake off. I recommend two coats a few hours apart. Works good as a surface protectant as well, stays translucent so you can see whats going on underneath it. A tip for applying: Spray it when the product is warm. Fill your sink with hot water (or boil a pan of water) and put the can in there to warm up the product. It lays down much smoother and evenly when warm.

Best rust protection for body panels in the Northeast
I live in the Northeast, a body man I know said this is the only thing that works to prevent corrosion in the rocker panels and wheel wells of a pickup truck. Been using it for a few years, it appears he was correct.

Four cans to treat a mid-size truck
I ordered this cavity wax to treat the interior surfaces of a boxed truck frame belonging to a gen3 modern Nissan Frontier. The truck has a boxed frame so I wanted to treat the interior surfaces of the frame with something to prevent rust. I also ordered the matching applicator wand set that sprays this stuff 360 degrees in voids. One can of this stuff was almost enough for a single coat for the driver and passenger sides of the frame. Four cans would enough to get the entire interior frame and the body panel voids of the truck. It dries to a waxy finish, like chap stick or lip balm. The extended spray wand reaches far inside the frame for good coverage. This stiff is pricey but worth the cost.
