FMX Try and buy a paint that is specified as a "chassis paint" like "Eastwood" sells. Many of the silver coloured paints that you can buy are not that great at holding out moisture. There is no real "chrome" looking paint that you can buy without a mortgage, however I would suggest that if you are going to buy paint locally that you go to a hardware store and buy spray cans of enamel spray paint for use on exterior metal railings---it will be silver coloured and have some durability.
