Working with lacquer paint


So I started painting some guns and decided to try and get an awesome chrome finish with using alclad 2; went to the website and see if they suggest anything on sealing it after its done and sprayed, but can't find anything there that would suggest otherwise. Wanted to know if anyone's used it or other lacquer paints and if and how you sealed it; or if I don't and won't have to worry about the paint coming off.
