Try the clear nail polish. Might be a little cleaner :P. Just don't get it into socket. Light coats on the side walls of the inner housing. Or better yet cut out small pieces of scotch tape and angle it inside. The Ref 1's I have seem to be rather tight fitting so no need to do it yet. I won't be changing out cables really so I don't think it will be an issue for me.
