Hey guys, this would be my first post, I'm a reasonably new cx500 owner. Putting some work on my 1980 custom. Was just wondering if someone knew the best method for cleaning up the engine block, mine has a fair bit of corrosion and doesnt look great. I would like to keep it semi close to the original look. I've already done the cylinder heads with alot of hand sanding and buffer wheeling but thats not really the finish I'm looking for. Any advice really appreciated, Included some photos as well. I'm a bit of a neophyte so I'm not sure if wire wheel and sand paper is even an option, preferably something I can do my self.
