3M Cavity Wax Plus, 08852, 18 oz (511 g)

Good product

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.

Great product for hard to reach areas! Shake along time before using!

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.

Used for all of my vehicles after repairing body and frame rust (get the extension kit to reach all of the interior areas). Three quick coats, as 3m prescribes, provides long lasting protection.
