Rain-X

I suspect it would Tony, although I am definitely NOT an expert! I say this on the basis that surfers wax the underside of their boards to make them faster by being more "slippery" to water.

Sharks, which have had hundreds of millions of years to practise this, have 'riblets' I think they're called, on the surface of their skin - little irregularities rather than being smooth and 'slippery'. Apparently that helps them slip through the water in ways that neither I nor the sharks fully understand.
I wonder if orange-peel on an E Type will help it go faster than a perfect paint job?

Maybe if it's underwater.
