Go to aircraftspruce.com and do a search on DC-4. This is a dow corning dielectric that is used for lots of things but in my case specifically for smearing on the oil filter gasket prior to installing it. Works much better than oil. When it's time to remove the filter it comes off without a wrench.Originally Posted by mbeach
This stuff is used on aviation oil filters and is specified for use on the side of Champion aviation oil filters.
