Thanks for that tip. I am a Fluid Film user and have wondered after entering the lighting field what the various uses might be. I used it a few weeks ago on Cast brass fixtures to see if it would prevent the white powdering. So far it has worked although that may be coincidental rather than a result. For those of you that don't know the product, it is lanolin-based. I am getting ready to put a coating of it on my work boots before I go out in our first snow today.
