white flaky stuff
Yes, I have used autosol and this stuff works. Done it on the top of the engine block and this stuff is making it a bit shiny. If I went further with a wire brush or fine sand paper, this engine head will be a shiny as any chrome surface unless you want to take it off and chrome it to perfection. Some engine heads have this brownish deposit which looks like spilt varnish or laquer and its usually badly applied if done purposely. If they had used a high temp satin or gloss paint, it would have looked supurb.
