Kbs Coatings 75101 Cavity Coater - 17.5 Fl. Oz.

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

Liked this product. I sealed the area located between engine compartment and the cab of my 1992 Ford pick up. "Water was leaking into the cab." These points were spot welded and the factory sealer was compromised this product kept me from removing the front fenders to make repair. Several applications were made over a 48 hour period.

Okay

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 like the tube to extend the nozzle. I was able to undercoat well into the frame of my old car.
