I used gummi phlege for the first time last weekend, treating the rubber and a few plastic components, and it seems as soon as it rained, away ran the gummi phlege. (In other words, it seemed like water soluble stuff.) the water also carried a bit of a film where it drained. I had a similar experience with 303 aerospace protectant, carrying a similar looking film when water hit it. Do you guys who use it notice the same?

I suppose gummi-phlege and 303 could be long-lasting in spots that don't get wet (like inner door seals maybe) or perhaps in climates where it doesn't rain? I'm wondering how people use these products.

If you wanted really long-lasting de-squeaking action, get some PFPE grease or oil (DuPont krytox) and smear just a tiny film over your squeaking rubber. It's good stuff - just very expensive and doesn't have the UV inhibitors like gummi phlege and 303. At least it will *not* wash off with water like 303 and gummi phlege seem to.
