PLEASE HELP ASAP

ive asked this Q before with about 3 replys but none of them really had anything to do with what i asked. so ill try again.

all i want to know is if anyone makes clear sealer to put over my two tone primer job i just did. if not what can i spray on it that wont cover the primer colors i have?

last time everyone said i dont need it or i shouldnt put it over my primer. so please dont tell me that

thanks
