Protek R is the ****

 

I just refilled my bottles and snapped a pic of how I have mine set up. Each bottle has about 6-7 ounces in it.







I keep them in some sort of plastic cover for a video game or something, I honestly cannot remember, I was going to throw it out and it looked like it would fit the bottles so I keep them stored in it. It keeps them tidy and fits between my battery box and side of the car inside. (Battery moved to rear)
