Bought a 5 gallon pail at a CAD, tried it before buying, liked that it was thick. Went to "decant" and the bottom has an inch of sludge in it WTF? My dealer claims it was a silicasomethingorother settling and offered me a free gallon and not replace what I had.Prochem said it would work just as good. Bullshit- it's not stable and it's missing ingredients. It's not even listed in the WHIMIS info off the website. I wonder what other shit is in without any knowledge to the end user?
