Chesterton products

I ran across a place wanting to unload a BUNCH of Chesterton products. Most of it is in 5gal buckets. They are selling them for $5 a bucket. I asked how much for all of it, and he said 400.00. There are alot of different products, but most of it is industrial degreaser, silicone(like the lube spray, not caulk), rust converter, pnumatic tool oil, & some kind of rust preventer. I am seriously thinking of buying it all. I don't want to buy a product that doesn't work though. A 5gal bucket of the "liquid wrench" stuff sell for 145.00. I don't think I would have a problem getting my money back, just wondering if anyone has used these products before. Here are some links for back ground:
