hey, dunno if you painted already or not, but a good thing to do is maybe sand down the entire thing VERY LIGHTLY, since youre using the paint that bonds to plastic you might not have to do that.
also. wash it off with soap and whatnot.. it'll degrease the plastic.
put it in some water to clean it off and then maybe air dry it if you have time. that way it'll stay as clean as possible. if you cant dont use paper towls.
hjope that helps
