Your cart is empty.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...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 And fenders, deck lids, tailgates...and more.

Works great and just as intended. People need to remember this is not a standard oil. This is a corrosion inhibiting compound(CIC) that is designed to cover a surface evenly and creep into corners and tight areas. The other reviewer mentioned that it smells and looks just like WD40 (this is not true) so i sprayed both side by side on a piece of 1/4inch steel to test them. In the photos you can see both sprayed on the metal. After an hour i dragged my finger lightly through each. I then repeated the finger drag at 5 hours and then sprayed both for 5 seconds with brake cleaner. Now this is not a very scientific test but as you can see the KBS is still there and the WD40 is all gone. KBS has tested this CIC out and claims that it will withstand up to 4000+ hours of salt spray which is awesome. Anyways I used this on the inside frame rails on my S10 after i stripped the frame and repainted it. You need to do any painting first tho and let the paint cure before using cavity coater. Hope this helps!

Use this in my door panels of my pickup truck after having some minor body work. Trying to make sure it done rust out anytime soon again. It's been a week and there's still a distinct order.Be sure to use this stuff on a public road or in a gravel driveway because it can leak out and if it does it will stain your driveway. Also after I did the door the first time I rotated the wand maybe a quarter turn or a little less and did them again to make sure I got good coverage. I also did the tailgate the same way.Hope this helps you!

The is a good product that is thin enough when applying to really get into tight, small places and soak in. One disappointing aspect was that apparently the unit had been on the shelf a while. When I stretched out the long tube it was a bit brittle and cracked right in the middle. I cut it off and put the nozzle on the shortened tube so all was well. Just couldn’t get a s far into places as I would have like to. Overall, very satisfied. Dries with a nice finish.

I had a little rust in my rocker panels of my jeep so I drilled 3/8 pilot holes and pushed the wand extend into the holes on each side then sprayed them as best as possible , capping with plastic plugs.In about a month or so, I noticed that no further rust has surfaced and the area that I did seemed to have been treated well enough to slow/stop the damage of the elements, I would use and buy again!

I love the idea of a simple cavity straw! And this is a good coating. But the straw is not as good as it should be. It started to kink pretty quickly, and most annoyingly, it kept flying out of the nozzle! Good thing I had goggles on, because I sprayed myself in the face no less than 20 times while coating all the cavities underneath the car. Why can't it be permanently affixed? When you combine the fact that it was kinked, it has some spring in it, and the fact that it kept slipping out of the nozzle, it got quite annoying.Edit: I ordered another one to cavity coat another car. The straw for the applicator was severely kinked on arrival! It was completely useless. I'm severely disappointed. Downgrading review, since this is a repeating type of problem.

I thought it would have been a little clearer than that dark brown.

Applies really well and it's simple to use, the sprayer works really well the first time. I had some leftover and wanted to use it again and had to clean the tip, no big deal, and it worked again.

This will save your vehicle from rust in the areas not coated with paint or sealer/primer. It works!

Right out of box the plastic applicator hose had a crack midway along its length. Had to cut it off and use at shorter length. Also found the hose kept popping off the can spray nozzle while using, wasting lots of the wax and sparying on me instead of target. Otherwise product looks like it will do the job ok. Hoped for more at such a high price though.

I purchased this product and when I went to use it I discovered that it does not work as it's advertised or supposed to work. I phoned KSB-Coating in the US and talked to Randy Tomak who asked me to take pictures of it after spraying. Randy Tomak admitted that the person who prepared the cans did not add the right amount of solvent (because of Covid-19). I asked him to send me a different can but he said I have to pay $55US. I wrote to the seller but they did not care to reply. Randy advised me to heat the surface that I want it to be covered with this coater!; this is the guru, imagine that? I wrote an email to Randy Tomak that KSB-Coating should recall all those cans that don't meet the right specifications; however, he ignored my message. Totally dishonest and unethical behavior. Canadians, don't buy this product, it is a hoax, it does not worth a dime.

I used the product to rust proof the inside of the doors and fenders on my 03 Dodge P.U. and liked the product just fine but I had to tape up the plastic wand to do the work.It got a little messy but I just used one can for now.I will finish the project in spring when the weather gets nicer as I still have one full can left.
