Cylinder head dyno shoot out

Do you glyptol all of the stuff you build? I’ve considered it but never have used it.
Not everything, but most stuff that's for me personally or if its requested by the customer. I have another process I use, it's a spray gun applied product called microslick by cerakote, it is claimed to be a "oil shedding" product, its pretty neat, oil just flows off of it, similar to rainex on a windshield. The main reason I use anything at all, is to prevent any corrosion while they sit.
