I got a couple cans of Glyptal to coat the inside of my vally pan and heads. Is there any reason I can't use it on the crank weights too?
I've found very little specifics on the net about oil shedding compounds for cranks. Even the sites that mention it and use Glyptal use a diffrent (expensive) coating on the crankshaft.
It's tough, slick, seals pores and puts up with oil. Why won't it work?

Are you building a top fuel motor or a car with a license plate?

it is fairly heavy and has been known to peel and cause problems...

better products out there today that don't cause a problem...it is only slick compared to an unpolished, rough surface like the valley surface.

I use Dem-Coat Red Insulating spray Varnish in the valley and on top of (iron)heads. Not sure I would use it on the crank. I believe Glyptal is a trade name of the active ingredient in insulating varnish.
