As promised, here are some pictures of my new Festool Systainer T-Loc containers on rolling bases.
The shorter stack is my day-to-day detailing stack. The Systainer 5 on the bottom holds sprays, the Systainer 5 on the top holds microfiber towels.
The taller stack is my oil change stack. One Systainer 4 holds 10W60 for the BMW. Another Systainer 4 holds 0W40 and 5W30 for the MINI. Both Systainer 4 containers have a bottle or two of Techron fuel injector cleaner. The one with the 10W60 also has Blackstone Labs oil sample kits. The top Systainer 5 holds new air and oil filters and my oil sampling pump.
