Walnut Shell Blast that engine!
I like the copper slag better, but I'm kinda partial because that's how aircraft cylinders look when they're new and unpainted.
The walnut shell looks like you ran it under a wire wheel and gave it that grainy "aluminum that's been wire wheeled too much" look.
If you go with bare aluminum, the copper slag will probably maintain its finish longer than a polished finish would.
Although, it would look nice if you accented some of the rough aluminum with mirror polished parts, like the PV window, water pump, flywheel cover, etc.
Another one for the nuts lol
Another walnuts...Not to hi jack but have you ever tried soda blasting?Soda blasting really cleans up well and also has a shiny type look.
I know it's Hard to Tell , Seeing the Head has a wrinkled finish , Maybe ill do the Stator Cover And post that.
