Having picked up a like-new steel frame I want to protect it as best I can, so I was planning on spraying the inside of the tubes with J. P. Weigle Frame Saver, a classic bike industry corrosion resist used inside of steel frames. Unfortunately, it’s now being manufactured from unobtanium. Digging for alternatives (and on the suggestion of David, from whom I purchased the frame), I looked into (and ultimately purchased, via a local distributor) Amsoil MPHD Heavy Duty Metal Protector.
Based on the descriptions of Frame Saver and how it coats and dries to a waxy finish it appears that this product will do the same with the same result. As a test I sprayed some spare sheet metal, uncleaned, and with a piece of tape on it to determine thickness as can be seen here. Frame Saver is reportedly a thin brown liquid that runs and pools yet still seems to cling nicely and this seems to be the same. Once I’ve seen how it sets up I’ll decide if the frame will actually get treated with it, but thus far the results are looking good. Also, at $6.60/can (16 oz) it’s considerably cheaper than the Frame Saver product would have been, had I been able to find it. J. P. Weigle Frame Saver was typically priced at ~$14/can for 4.75 oz. With this I should be able to do my frame then let any friends who pick up steel frames use it as well.
