Varnish won't help and may deteriorate because of the
ultraviolet given off by the CFL. The shatterproof
incandescent bulbs I've seen were coated with silicone
rubber sealer , and should be able to brush clear
silicone onto a CFL, but maybe you'll have to thin out
the silicone with alcohol. Also Loctite/Permatex sells
a thin silicone rubber sealant designed to be very runny
so it seeps into gaps around car windshields to seal
them. 3M has another product like this, only it's not
silicone based. Try contacting Loctite or 3M because
they're really good about giving out information.
