CRC 3-36 Multipurpose Lubricant & Corrosion Inhibitor 03005 – 1 Gallon, Corrosion Protectant w/ Petroleum Base for Metal Equipment

I used to use renaissance wax on my cast iron, but I always battled surface rust given a short amount of time.I have now changed my practice, and use this CRC 3-36 product now. For the first time, I spent a good amount of time with a green scrubbie and making sure as much could soak in and lift off any dirt or grime that had been there. I then left a film on the cast iron overnight, and wiped it the following morning.So far, I've used it on my bandsaw table and lathe bed ways, as well as on my hand planes, and it looks great. I used this recently when refurbishing antique stanley hand planes, and it worked great as a sanding lubricant as well as cleaner to help lift off rust and prevent future rust.After I finish using a tool now, I keep a towel with CRC 3-36 soaked in it, and I do a wipe down. I expect this to maintain the condition of my cast iron machinery and hand tools, as well as keep them smooth to reduce friction and sticking.I opted for the gallon for value, but I don't use it directly from the gallon bottle. I poured from the gallon into a spray bottle, and that is what I use directly.So far, I think it is a great product. If anything changes in my experience, I'll update this review!-------------2/14/21 Update. I'm just about out of my first gallon, which might seem quick, but I've found many additional uses for this product.I got into chainsaw milling and have an MS661 with a 32" bar, 36" bar, and 56" bar with my Alaskan Mill. In total, I have around 15 chains in the rotation plus the chains for my smaller saw. After each use of the chainsaw, I clean and store the chain with a coating of CRC 3-36. This has helped with keeping the chains and the bars in good condition and preventing corrosion.I will say that when I'm turning freshly cut red oak on the lathe, the moisture that is released when turning as well as from the chips that land on the lathe bed can corrode through the coating of CRC 3-36, so I still have to be quick about clearing chips and cleaning the lathe bed when I've finished the rough turning of the green wood bowl blank.All that to say, I have a second gallon now, and I plan on continuing to use this for as much as I can to prevent corrosion and lubricate.

Hey it's CRC, what is left to say? This is an excellent product. It's great especially when I am working on just about anything mechanical. I worked in manufacturing and robotics and have used just about every brand on the market. I'm working on some legacy steel frame road and mountain bikes and this stuff is very good for stuck and rusty fasteners. I use a dry film lubricant for chain and cables. But this stuff is unbeatable for those metal fasteners that haven't been removed since the 90's. This product I highly recommend.

A woodworking magazine tested a number of these corrosion inhibitor sprays, (including Boschield) and this one was rated #1 for rust resistance. Significantly cheaper than some of the others, and is very clean and very mild odor when compared with WD-40. I wipe down handtools and cast iron tops with this stuff after use and it has worked exceptionally well, and there is no silicone to hamper wood finishing. My last can lasted me over two years.

Great lubricant

I bought this to spray all my tools with to keep the rust down. It's a little expensive, but it works better then most products I have tried. I have since come up with a home brew of ATF and acetone that I like better, but I will use this as a light oil for rusty bolts.

Works good nice light film protects quite well

This product is a little expensive but SO worth it. It's a definite must try.

Goes on fairly light but protects for months. Very versatile lubricant. I like it better than a lot of the wd40 specialty products. Less toxic overall, I believe. And not too expensive

used for undercoating. Liquid creeps into tight spots
