I have more silicone 200 than I know what to do with. I have used it to magically make scratches disappear! It works wonderfully. And yes, it helps with dust, some.

Immersing your film in it can be very messy if you don't have the proper carrier. Of course condit made them, I've seen them form time to time on ebay. I should say it is also messy with the proper carrier :-)

If you are interested I could probably part with some of my silicone for a small charge to help offset the $150+- I paid.
