RTV - Waterproof
(OP)
What do you all think about using rtv as a waterproofing agent? I've got a small potted pressure switch that is only IP65 rated. Problem is, I need to submerge it (IP68 rating), and it does not quite work that well. For the most part it is waterproof, but there is one small press fit square piece of plastic that is allowing water through. My initial thought was to use a small coating of rtv to seal it for water resistance.
I have found no good reason to not do this. But wanted to see what others thought. No one in my organization really has any input on it....

It will be highly dependent on surface preparation and goo application.
I would be unlikely to approve it if offered to me by a supplier.
RE: RTV - Waterproof
If you can do some testing to demonstrate the durability that may make folks more willing to accept it.

I'm wondering why you can cut a gasket to do this.

If the plug can be removed, coated with the RTV, and pressed back in, it has a better chance of working.
... all highly dependent on details, of course.

Additionally, all of the anaerobic types will attack (craze/ crack) many/most plastics. I'd want my Loctite rep to bless the application before going ahead.

I think I have enough info between this trail, and my own research to intelligently make a recommendation to my customer that is favorable to my needs.
I appreciate all the feedback from everyone!
