An operator I know is remodeling his tunnel. He only has room to put one additional arch in his short tunnel. He is not sure if he wants to put in hot wax or one of those super sealants like RainX. I have a personal bias in favor of a super sealant because it affords more protection than hot wax but I know hot wax puts on a better show in the tunnel. If you had to choose which one would you pick?
