Cavity Coater is a one-step, super-penetrating corrosion inhibiting coating (CIC) for long term protection on all metal surfaces.
Cavity Coater provides a self healing film which renders over 4000+ hrs salt spray protection (meaning Insane Rust Protection) ...over 4 times the protection of conventional cavity waxes.
Use Cavity Coater with a KBS Cavity Wand to give long lasting protection for those hard to reach enclosed cavities such as rocker panels, boxed frames, inside doors & fenders, deck lids, tailgates...and more.
Automotive: Boxed frames • Rocker panels • Inside doors • Inside car & trailer frame rails • Windshield cowls • trunk lids • Hoods • Inside A-Posts • Inside B-Posts • Inside front & rear fenders & Inside tailgates • Back sides of bumpers • Weld seams (Wicks into welds & seams) • Insulating between unlike metal surfaces • Use wherever a typical cavity wax would be used.
Anti-Seize/Anti-Corrosion: Nuts, bolts & screws • Shafts • Pipe fittings • Gaskets • Press fit assemblies • Valve assemblies • Taps & drills • Pump mountings • Packing glands • Chain drives • Metal fittings • Machinery

This product works very well. I followed the directions as per System Sampler video on You Tube for fixing the pinch welds on my truck doors and tailgate. I may have used a bit too much, as I did have more weeping from the door drain holes, but the wand does provide far superior coverage than does the Eastwood Internal Frame coating (as I have used that product on a different application) and it cleans up easily. I am glad that I found KBS Cavity coater, and it will be the only product I will use of this type. I will be using this also on the lift gate of my SUV. This product is DEFINITELY the way to go.

I use this cavity coater on my boat trailer used in salt water. My first trailer (Galvanized steel) just melted with rust after 10 years. I spent $4,000 on a new Aluminum one and have coated this one Steel parts with this product and over the last 3 years I have extremely little rust. This cavity coater works for me.

So far, I've used KBS Cavity Coater to treat the inner front fender cavities of a '98 Lincoln Town Car. Removing the headlights provided easy access points. I applied KBS Cavity Coater using the extra long wand and the application was fast, easy and painless. The product has a fairly pleasant smell. I chose to apply the product generously but have plenty left in the can to treat the bottoms of the doors and the inner rocker panels. I will likely order a second can for the inner rear quarters and inner frame rails as I plan to treat the entire car. Thank you for putting out a great product in the fight against rust.

Great solution for hard to get t places. Recently refurbished the roof on my 1964 Mercedes 230SL. There was an "impossible to reach" channel in the back lower portion of the roof. The cavity coater was perfect for the job. I was unable to use the spray head provided but was able to plug the end with a toothpick and drill tiny holes in the tubing. Worked perfectly!
