GLASS BEADING INSIDE OF VALVE COVERS AND OIL PANS

Soda blasting works well, but you must thoroughly clean very well. I had my brand new NHRA Pro Stock chassis soda blasted and when it was electrostatic epoxy paint every place that had a particle of soda remaining left a depressed puck mark in the paint.

I also use molasses, but it must be farm grade molasses that is sulfated. The sulfur makes the reaction work. Human food grade will not work because it's void of sulfur. Also I would never mix it to a 50/50 ratio. I like to use a 1 part molasses and 5 parts water. It removes rust, but does nothing to oil, so you must be oil free before dipping the parts in the mixture.
