Does it work? Sort of...
Is it worth applying? Maybe...
I'll share my thoughts, but I'd suggest asking the folks at daVinci for a recommendation.
My thoughts, frame saver isn't a bad idea, but to be effective what ever you use -- JP Weigle's stuff, Boeshield T9, or any one of a number of other products that will flow into and stick on to your steel frame's tubes -- must be reapplied on a regular basis, e.g., each year or so depending on your climate and if you ride your bike in wet conditions.
Because of how it's used, it does tend to be something of a placebo for most folks who go to the trouble of having the unseen, insides of the tubing on new steel frames coated with the stuff but who aren't aware of or don't bother to reapply. As for rusting out, I'd say that the likelihood of a rust-through has actually gotten higher over the years as the tubing used to build bikes and tandems has gotten to be much more thin that it once was. In other words, while it's pretty clear that a 75 lb Schwinn Town & Country tandem from the 50's will never rust through, I'm not sure the same would be true for an air-hardened, superlight alloy steel frame produced today if it were ridden on wet roads treated with salt and parked in an unconditioned shed, garage, or storage building where temperature changes could cause condensation to occur within the frame.
My personal practice???
Our '98 Erickson is steel and has never been treated and I will occasionally find surface rust in the seat tubes which I clean out each year during it's annual overhaul. Getting into the other frame tubes is nearly impossible so I've never messed around with treating it. My '98 Erickson single bike, on the other hand, does get retreated with Boeshield T-9 every couple years because I have access to the main tubes via the head and seat tubes and bottom bracket.
Our '02 Erickson travel tandem was steel and it received a coat of JP Weigle at the builder's shop because being a take-a-part, it's easy to do. I would periodically re-coat the sticky residue of the original JP Weigle stuff with Boeshield T-9 during the annual overhaul.
