Most of the case has ET22 anchor epoxy on it. There is a skim of JB weld on the outer surfaces. The ET22 by Simpson is like glass when hard and it falls into porous castings easier. It’s real runny and you can easily pour more on top for layers.
The flywheel hits the case! Removed the fan from the flywheel and removed 2mm off the steel skirt of the flywheel with a surface grinder.
