I bought a new 5 gal. pail of Thompsons the other day to finish my deck, I opened it up and its milky! What gives my other (older) single gal is clear fluid. The look of the pail is the same but the product seems to have changed. Any ideas on this. I don't like the milky product, I tested it on a concrete section of my patio and it is now blotchy. Yet a section of the patio done with the older pail looks fine.
