We have just received a shipment of the Airboy Undersealer Guns direct from Denmark. These guns are of excellent quality and are a great way to apply Prolan Liquid especially to the chassis of machinery/ trucks / 4 WDs, motorhomes etc. The airboy Gun comes with a 1 metre hose which is excellent for reaching those small areas where corrosion is a problem e.g. boat trailers.
