I have a 32oz. bottle of concentrate. makes a gallon with distilled water. I've already mixed up a 16 fl.oz bottle, and used it once to clay a mazda sedan. so the bottle is about 1/2 gone. so, there is quite a lot left
I'll do a 1:1 trade as I have a little under 1/2 gal of Last Touch left if no one takes you up on it. I love OID hehe 16oz concentrate for 16oz concentrate? Let me know bud!
