67/68/69 cuda dilemma

Also, i dont have a problem putting the evaporust on it late in the evening, then going to sleep for the night, then cleaning it off in the morning before work, reapplying it if need be, and then going off to work. If I am either sleeping or at work while its doing its job its not like i am there impatiently waiting for it to do its thing. Also i am thinking by showing this product on my build thread, and how to use it to maximize its efficency w plastic sheet, i may be able to help others with similar issues that dont have access to gee whiz stuff like pressure pot blasters etc.
