RCP's 18" Flagged Nylon Truck Brush is engineered to wash large vehicles efficiently while treating paint gently. The durable nylon bristles feature flagged tips that split at the ends to increase surface contact, holding more soap and lifting dirt, grime, and road film more effectively than standard bristles. At 18", the head covers big panels on trucks, trailers, and RVs quickly, and the design works with compatible wash poles and flow-through handles to deliver water right where you need it. Nylon construction stands up to repeated use and harsh cleaning chemicals, making this brush a workhorse for fleet and commercial washing. Pair it with your favorite RCP wash solution for a streak-free finish that won't scratch. When you need to move fast across large surfaces without compromising on a gentle, thorough clean, this flagged nylon truck brush gives you the reach, coverage, and durability to handle the job.
