This gun simply screws onto a standard tin of underbody coating material and creates a venture action that sucks up the material and pushes it through the gun nozzle. An absolute must-have for anybody or workshop applying underbody material to vehicles, also a great tool for DIY and classic car restorers. Comes complete with plastic extension probe for reaching into those difficult to access areas.
