Rust Protection Cavity Wax 5 Pack with Free 20" Wand

I used this product to coat the inside of a Jeep Wrangler JL frame. I probably applied it heavier than needed. I used 4 cans. It coated very evenly, and dripped out of drain holes in the frame. It gives me a good sense of security as far as preventing water infiltration.

I've worked with 3M Cavity Wax which dries as a solid. This does not dry as a solid but I'm hopeful it will provide rust protection. Similar products have good long term reviews. The price was good and there was no bad smell. Similar products require repeated applications every year so I'm assuming this will too. Some of the spray caps clogged but the kit came with extras. It took about 3 cans to complete my truck but it's good to have extra cans. I would probably use the 3M product to protect autobody welding and restoration purposes but for general rust protection this seems fine. It can be wiped off if you need to work on the vehicle.

If your looking for quality cavity wax buy 3m this stuff is like water

This was applied according to label directions. It has never formed into a WAX.Instead, it is a thin oil. I am disappointed in this product.I should have spent a little more and bought 3M.I can provide pictures.

Seems thin, but does job
