Great product

Inexpensive and does exactly what I want. It was a corrosion/rust preventive that you spay all the drain locations of the doors, trunk, hood and remaining body locations. Look at how to use it including YouTube etc. Keeps my new car from rusting for years and years. ????????

So Easy To Apply

When I started thinking about coating my frame I was concerned with the inside thinking that even I coated the outside of the frame the inside would still rust. Found this. So easy to apply and I liked being able to see if weep out when the entire inside had been coated well. High Recommend.

This stuff works!

Looked at many rust prevention coatings on the market both on line and the auto stores, this coating by far is the best. The ability for the coating to creep and flow into tight areas before turning viscous is what makes this product work. Used this on a 3"x2" box style frame Shorelander boat trailer after repairing some rusted out sections. The extended wand allowed for a complete coating on the inside of the frame along the entire 24' length using the wiring holes in the trailer.

Great Solution

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!

Great product. Easy to use & goes a long way,

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.

Preventing rust beats de rusting and painting

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.

Works Great, Wand is Superior

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.

Woosh!

Boy this stuff comes out F-A-S-T, making a giant mess if there's any way for it to escape from the cavity. You can almost use it to hose down parts while you coat The up-side is, I was able to coat the outside of my parts too - using the leftovers I had to mop up with a rag. Don't take this wrong, I like the product, just wasn't prepared for the mess.

I HAVE to review this!

I usually don't leave reviews, but this is a pretty good product. Tried it last year on a project and was impressed, so I've been doing some testing here recently. Sprayed one light coat on a new piece of flat steel, and 6 weeks later the coated area looks new, while the uncoated area is surface rusted. It's seen plenty of rain and sun in 6 weeks, and a bit of ice this week. I keep damp about once a day and water beads right off the coated section. Totally dry and has not left a film, but still protects, pretty awesome to me. I'm a mechanic by trade and the cavity wand is awesome to reach the impossible. Try this stuff!!!
