I have a bottle QD and glass cleaner along with MF towels. They're in the same bag with my compressor, tire sealant and some basic tools. I store it all in the spare tire cubbyhole.

I keep a micro fiber towel in the car and a bottle of Quick Detailer. It's good to go over the car after a wash and dry with QD to get any water spotting that was missed and it leaves a nice finish. Its also handy on trips for a stray bug or bird dropping. Good Stuff!
