Why?

scratches = rust

Kinda defeats the purpose of coating the cast iron.


1. Isn't cast iron much harder than aluminum?

Than anodized aluminum? Aluminum is certainly harder than Boeshield.
2. How is one smoothly polished, soft metal going to scratch anything
let alone a much harder metal?

It does. My aluminum miter gauge certainly scratches the top.

You have some remarkable aluminum (or wierd iron), aluminum is much softer
than iron. Here's a Moh's scale...
