The black paint on my engine has patches that have chipped off, I am left with sliver patches on the engine. I am thinking of either getting touch up paint to fill the gaps of stripping the paint off the engine and try to polish it. I am not to sure which of these would be best. I have a feeling to strip it and polish I would have to pull the engine out to do it properly. I am a little worried if bare steel would be exposed from this. Any ideas?
