Actually, a good sealant does double-duty as strain relief, and is 
probably the better choice unless you need frequent access to the 
connection (so boots are better for battery terminals). You just need 
the RIGHT sealant. Anything designed for electrical use is probably 
fine. I think Bob Nuckolls (Aeroelectric) actually swears by Shoe Goo. I 
can't confirm its contents, but I've read several statements that say it 
doesn't contain "corrosive" elements. Might be a fast, cheap solution 
you can pick up at any mall if that's true.
