If is just painted gray then the other option is to chemically strip the gray paint off and if then it the original is black take the shine off with some 400/600 grit sand paper

Maybe you are right. It is a black material, I may be able to sand it carefully (I do no think chemicals will do it any good).

Get it at an automatove store. Best spraypaint for plastics, period. Takes less to cover than traditional rattlecans.

I would solve this problem myself by selling the gray hood and getting the right one, but if you want to solve it by painting it use flat black fast dry enamel spray paint. Forget about hobby shops, model paints are designed for show but not for go. I do toy modifications as hobby and wouldn't recommend any of the Testors paints including the Model Master series. In short time after exposed to sunlight you would have a 'whitish, milky' finish on your hood.

I don't understand why you would want to go to the enormous effort of trying to strip off the gray either chemically (what chemical would you use that would somehow strip off the gray but leave the black underneath and wouldn't damage the hood ?) or trying to sand the gray off to get back to the black. Its unlikely that either of these methods will leave you with a lens hood that looks good.

Why wouldn't you just lightly spray over the gray with matt black. This would be very quick and simple and (if you are careful) will leave you with a decent looking lens hood.

Paint for plastic models from Tamiya etc are safe for plastics but, as someone noted, may not be very hard wearing. Auto paint or ordinary enamel sprays may be more resilient, but check they don't attack the plastic - if that is what the hood is made of.

I wouldn't be attacking a lens hood with 400-600 paper. If you are trying to get the gray off it will take forever and leave a rough result, and if you are just trying to prepare the surface for painting you might be better of with something finer than 400-600.
