Engine Paint Colour Match

Hi.

I posted on here a couple of weeks ago that I have got corrosion on my O/S engine casing. Does anybody know of a good colour match from Halfrauds or similar? ie. regualar metallic car paint. I might use the same paint to re-paint my fork lowers as the rot has started on these as well. Not sure if I can be bothered to polish them, although it does look cool when done well.

On the same note how do you remove the plastic covers at the top of the fork lowers that protect the first couple of inches of the front face of the fork uppers?

Thank you for any help you can offer.

Tim.
