M16 Bike Guard £12

www.m16extreme.com POLISH RESTORES PAINTWORK but to protect properly it takes a wax or ceramic sealer. That’s what this spray-on finish for helmets and bike paint does, adding a sheen and promising to form a tough protective layer that will keep dirt off. I’ve used it on two bikes and water certainly beads effectively on it, running off and taking light dirt with it. So as well as making the bikes look good, it also make cleaning easier. Great.
