I am trying to get into detailing professionaly on a part time basis, mostly for local Mustang and other car clubs and possibly faculty at local colleges.
This is just a small portion of my "inventory". These are my most frequently used products and things I am currently testing, the rest is in bins stored in a closet. I like to experiment with different products hence the wide variety.
Its in the garage in another cabinet I also have a Makita rotary with a backing plate that allows me to use the same 6.5" pads that I use with the PC.
The pictures above are 2 cabinets in our laundry room that I kind of took over. I also have 4 18 gallon rubbermaid bins in a downstairs closet full of stuff as well as the products that are in gallon sizes in the garage.
One of these days I will be able to remodel the garage and put cabinets in there. I only have half the garage right now since a lot of our stuff is stored in there. We are planning on building an addition onto the house later this year and then I will also be able to remodel the garage.
Here is a quick pic I just took (sorry it was dark out and I couldn't get enough light)
