urethane base mixed with sealer?

has anybody here successfully mixed a urethane base and a urethane sealer to have a tinted color sealer? if so how did it go?

hey man i have always done this to tint my primer.i can only get a gray primer where i live.i know they used to make a white,which whould be better.         but i use a gray 2 k and mix a single stage color in to it.i like the way it looks and it wont fade like primer will.i spayed a guys toyota 2 years ago and its just now starting to show a little fade.but yeah i have done this a few times man.i just did my wifes truck in a pink primer and it turned out nice.i whould post some pics but i dont do that so.        anyway i am happy with it afterwards.
