RCP's Bi-level Truck Brush Blue Nylon is a must-have for washing and prepping all types of vehicles, including freight vans, trucks, boats, and trailers. The densely filled fiber is staple set into a durable foam plastic block with a single threaded handle hole, and the bi-level design helps the bristles follow curves and contours for a thorough clean. We recommend pairing it with a flo-through handle (not included) so you can scrub and rinse simultaneously, using the 10" length and 2-3/8" trim to cover wide areas quickly. The high-quality construction stands up to repeated heavy-duty use wash after wash. This brush paired with a flo-through handle and a quality wash solution will take your washing experience to the next level.
