After getting my 1957 235 head back from the machine shop I sprayed on Eastman paint prep to get the, what I thought was an, oil film off before painting. The more I sprayed and brushed the more metal colored stuff kept coming off. After spaying two cans of the acetone I'm getting close to it being clean. I'm very new to this, my first head from a machine shop, so I'm wondering if this is some kind of clear coat or cast iron colored paint on it. I'm now hoping I didn't screw this up.
Anyone know what's this is about, or words of wisdom?
thanks,
Paul
