I have heard some good things about "The Solution", that they call the world's best wateless car/rv wash & protectant! Also; they now have a waste digester or holding tank treatment for both grey and black tanks called "Piranha"! Talked to a couple of people who say the stuff works better than any other on the market! Has anyone else heard anything about these products and if they really do the job? Their website is super-seal.com Give me some feedback as I am considering selling these products to help out with on the road expenses if they are top notch products! Let me hear from you guys & gals.
