You have to watch out using Rain-X. The bottle says it's not safe for some plastics. There is a product that goes by the name Fog City Fog Thing. They are laminate sheets which you apply to the inside of the shield and work very well. Although you could experiance some distortion in your view if not properly applied.
Fire hydrant caps are painted different colors to allow firefighters to quickly identify the flow rate of any fire hydrant. Knowing the flow rate of a fire hydrant tells them how much water it can provide for firefighting operations. The four basic colors of fire hydrants and their respective flow rates are listed below.Red fire hydrants have a flow rate under 500 gallons per minute. Yellow fire hydrants have a flow rate between 500 and 999 gallons per minute. Green fire hydrants have a flow rate between 1000 and 1499 gallons per minute. Blue or light blue fire hydrants have a flow rate of 1500 gallons per minute or higher.
