KBS Cavity Wand - 36-inch 360-Degree Spray Applicator for Cavity Coater Aerosol

The KBS Cavity Wand is engineered specifically for use with the KBS Cavity Coater Aerosol can. The Cavity Coater Aerosol is sold separately and is not included with the Cavity Wand. The wand snaps directly onto the aerosol valve without any adapters or additional hardware.

The Cavity Wand is engineered to fit through a 1/4-inch (6.35 mm) hole. This means you can often use existing factory drain holes or rubber plug openings without drilling. When drilling is necessary, a standard 1/4-inch bit is all that is required, eliminating the need to cut large access holes and minimizing any modification to your vehicle's body panels.

Attach the Cavity Wand directly into the valve of the KBS Cavity Coater Aerosol can. No tools, clamps, or adapters are needed. Once attached, insert the wand tip into the access hole and depress the aerosol valve to begin spraying. For a visual walkthrough, watch the "How To Attach Cavity Wand" video on this page.

The Cavity Wand is effective in any enclosed metal cavity accessible through a 1/4-inch hole, including rocker panels, door skins and inner door cavities, quarter panels, B-pillars, box-section frame rails, and cross members. It is equally useful on trucks, SUVs, classic cars, boat trailers, camper frames, ATV frames, and enclosed agricultural equipment tubing.

For maximum interior coverage, insert the Cavity Wand to the full depth of the cavity while spraying, then slowly withdraw it while continuing to spray. This double-pass technique, once going in and once coming out, ensures all surfaces including the far end, the side walls, and the area near the access hole are fully coated. The 360-degree rotating tip handles the full circumference without any need to rotate the wand manually.

Yes, the KBS Cavity Wand is designed for multiple uses. After each application, flush and clean the wand immediately per the directions included with the Cavity Coater Aerosol. Cleaning promptly after use prevents product buildup from hardening inside the tip and extends the life of the applicator for future projects.

The KBS Cavity Wand is designed and tested for use with KBS Cavity Coater Aerosol. Using it with other aerosol products may produce inconsistent results, as valve size and spray pressure vary by manufacturer. For guaranteed performance and compatibility, use the Cavity Wand exclusively with KBS Cavity Coater Aerosol.

Generic cavity wand applicators typically spray in a single fixed direction, requiring the user to rotate the wand manually for any degree of coverage. The KBS Cavity Wand features a true 360-degree rotating tip that covers all interior surfaces in a single pass with no manual rotation. Combined with its 1/4-inch access requirement, which is smaller than many competing applicators that require 3/8-inch or larger holes, it minimizes body modification while maximizing coverage.

After applying KBS Cavity Coater to the interior cavities, allow the product to cure fully per the Cavity Coater directions. For exposed exterior metal surfaces adjacent to the treated cavities, apply KBS RustSeal as a permanent topcoat barrier. Replace any factory drain plugs or rubber grommets after curing. Clean the Cavity Wand immediately after use so it is ready for the next application.
