When you buy the five litre tin(like an oil can), buy the spray gun too....its like a spray lid off kitchen cleaner bottle with a long hose. To get the gun to work the waxoyl needs to be thin. You do this by standing the tin a red hot water in an old washing up bowl or bucket. Every few minutes ya need to shake the tin. As said above the stuff gunks the gun up so it stop working....easy to solve. Leave the tin stood in the bucket of hot water and move it round with ya.....just need the car high enough!

Make sure you either remove or mask the exhaust!
