I've read on here the best way to winterize aim command is with RV antifreeze. I was wondering how much i needed to put in the tank for a 90' boom. Also can you mix it 50/50 or do you need to put it full strength. How long do i need to run the booms to make sure it gets in all the nozzles. Also do i need to winterize the rinse tank or can i just drain it. Thanks for all the help.
