Dual Chamber Trigger sprayer bottle - Each chamber can hold 230ml of each solution. We would not recommend spraying anything larger than an average sized motor bike tank.

Advantages- Low investment, quick set up times, easy to use, rebuild kits are available. 

Disadvantages - Silver can form on the wet internal parts so need to be stripped and cleaned after each use (about 10mins), transfer efficiency of solutions can be a little wasteful, can make your fingers cramp up when doing larger items.

Dual chamber suction feed air gun - Each chamber can hold 950 ml of each silvering solution, great for larger items.

Advantages - No need to clean out after each use, the whole unit can be stored for 3 months in a dark place in between uses.

Disadvantages - Set up times can be time consuming setting up for the 1st time, transfer efficiency is not to good, a little bit clumsy to use, a bit weighty on the arm for prolonged periods of use.
