Hi and welcome, do you know what sort of paint he used to mess up your kit?
, do a search on the forum about paint stripping, it might be your only option I'm afraid to say. If you need to paint trim in silver, go to an art store and ask for a fineline marker, in the UK there is a brand of fineliner pens made by a company called PENTEL, they come in gold and silver, they are supposed to be used for decorating greeting cards but they are really good for detailing small parts
, I use them all the time. I hope you find what you're looking for and my post has helped you out in some small way, and by the way, military modellers only paint in matt/flat colours anway, gloss to them is sacreligious
