Hmm I dont know about the 32, I went right for the big ole
gallon sized since I use it as quick detailer too.
But 32 should be good for at least sixteen washes. I believe your supposed to use 1 ounce for 2 gallons of water. But I always use at least 2 ounces to play it safe.
here's a great waffle weave towel for drying after a No Rinse wash. The threads don't snag like most waffle weave drying towels I've used. Their silk bind mega towels are good too. These guys always toss in an extra towel with an order of $50 or more. The 12 pack is a good deal, I try never to pay more than $4 per towel for a high end paint towel. The wheels, glass and interior get the
cheaper towels.
