4D Reamer Rentals LTD. has a long history or providing quality tools for gunsmithing.
Recently they provided me with a test sample of their latest product. Its a release agent for use with glass bedding products. I have tried it with several bedding compounds and other epoxy products. Results have been great, not only does it release as any such agent should, it does so with no oily film either on the metal or the stock.
I’m not going to tell you this is the “only” release agent to use. But is has a couple of advantages I want to point out. First, it is a green product. I don’t buy into everything about the green movement, but I do like to use products that are not hazardous to my health. I figure I am exposed to enough junk on a daily basis, there is no reason to purposely add to the mix.
This product is at worst a mild irritant. Some similar products require hazard fees to ship, 4D’s release agent does not. They ship it with a sprayer that makes it easy to apply. You just mix the concentrate they ship 4 to 1 with Isopropyl alcohol (which the customer provides locally) and put it in the sprayer. It takes a short time to dry, that is probably the one down side. I just sprayed the parts before I mixed my compound and the parts were ready to go by the time I was ready for them.
The professional grade spray system that comes with the release agent has countless applications, disposable, recyclable, easy to clean and where no compressor is available its a God send. 4D sells the sprayers and replacement parts separately too.
How the sprayer operates is simple, release agent, liquid, or paint product is pulled from a removable, refillable Product Container. The pressure comes from the top part called the “Power Unit”, contained separately from the “Product Container”. A dip tube runs through the Power Unit and into the Product Container pulling up whatever you are spraying.
The product container is a glass bottle with graduations so it’s easy to mix or measure the product you plan to spray. This is a great option for somebody who does not have a compressor or needs a field expedient solution. I like this product.
