Spraying head gaskets.

[Chassis 33]

I know not to believe everything in print,so want to sound this one out. I'm reading through one book on engine building and it mentions that unless the manufacturers instructions explicitly say not to, you should spray headgaskets in aluminiumised paint both sides prior to fitting. Has any one any views on this and the logic behing it.

Thanks for the replies folks, didn't expect quite a debate about it!! For reference the book in question is http://www.amazon.co.uk/Engine-Builders-Handbook-T... and the author is talking about new gaskets.
