Take this with a grain of salt (no pun intended... winter weather thread), but I found that there's no quick fix better than a sacrificial grease layer for sealing up close-fit assemblies in auto mechanics. I've packed areas with thick synthetic greases with low susceptibility to wash-out with success (ex. green grease). Of course, this will require you to go back and clean out/re-grease on occasion.
