I have a 1.8 OE muffler that looks and sounds solid, just has black paint over surface rust. I want to clean it up and repaint it OE gray. I can either media blast the entire thing, or take it to my local metal cleaner and have them submerse it (much easier for me).
Question... Is there anything on the inside of these mufflers besides metal baffles? Is there non-metal dampening material that will dissolve if submersed?
