Peter got back to me and said the following:
I have been using Blu-Stik for 20 years. It is less aggressive than cross-linked silicones and does not snap cantilevers as the other products can if the arm is raised too quickly.
A VERY thin coating on a quarter works best.
The tiny amount of oil in the material does NOT wet to diamond – diamond sheds oil. It is not like a “wall” in terms of its affinity to oil. The oil in fact helps to clean the stylus.
My opinions now:
I'm hoping that the DAP product doesn't do what the Moongel did to my stylus. Being that the DAP is more of a solid unlike the gel the Moongel is, it may hold together better than the gel and not break down as readily leaving residue deposits on the stylus, only a slight oily film that is repelled.. Peter said the oil in the DAP doesn't wet to the diamond, that the diamond repels oil. But I wonder if the oil will build up with dirt from the grooves that may have stuck to the stylus, causing a crusty deposit. Only way to know is to try it myself, but I won't use anything oily anymore. Hoping my concerns are a non issue and that I never hear of the DAP casing any problems.
