Intake Manifold Coating

[aonghus]

A while ago I read about a coating that specialty coatings out of longbeach was using that was clear, never yellowed, and was nearly invisible (so thin the coated item wouldn't appear to have a clearcoat)

I think I read it on one of the popular mag sites, anybody read the same thing? if not, what can be used to keep a new cast intake looking new... I'd prefer it not even look as if there is a coating on the metal.

thanks guys, apologies if this is in the wrong forum
