HELP! Mercruiser riser exhaust gasket surface won't clean without damaging surface!
Doing some maintenance on my boat which required to pull off the exhaust risers.
Its a carbed Mercruiser 465hp 502
The exhaust riser gaskets seemed to have an antisieze gray type coating on them, and they came off easily with no issues.
The issue now is that I'm trying to clean the gasket surfaces and nothing is working. It seems as though the gasket surface was powdercoated which I have never seen before. I can't get aggressive with stripping the gasket material because the aluminum is soft and I don't want to damage it.
Any info on whats going on here or what I should do?

CArb cleaner and sharp razors. Take's a bit but you won't reove any aluminum.

The coating was so thick and tough all the wire brushes and wheels were doing was marring the aluminum. All is good now!
