I am working on this quick project (waaaaay over due). it involves a gear that I either want to paint or powder coat. problem is, this gear has had a hard life in an engine in it's previous life. I believe it was a cam gear. Needless to say, it has been bathed in oil at high temps. I am not sure paint will stick. I saw a blog post where a guy powder coated a set of used brakes... after cleaning them, he heat soaked them in an oven for awhile.
Does this actually work? Recommendations on how I can give this ear some color?
