I finally converted my foam n flow to a rain bar on my RZR 3. I mounted the foam n flow pipe up underneath the stainless shield and turned the air pressure down. The coverage is so much better now. I also bought the red LED light that goes on the RZR 4 and mounted it to the cover. I had the old hockey puck style LEDs before but they don't last but about 6 months. Im thinking about converting my RZR 4 to a rain bar also. The wax curtain is something you have to tinker with every week it seems like.
