I'd stick with original design, but silicone or even JBWeld is not a bad 
idea -- I've lost them on my MGA before. According to my mechanic, the trick 
is to start at the center and then pound in increasing circles out towards 
the edge of the plug -- I use a six-inch socket extension. Lots and lots of 
little taps. When you're done, the plug should be domed inward, not just flat.
