Not sure if they will effect each other or not. Just keep in mind you will never really be able to fluch ALL the merc out. Therefore some will still be left in the valve body, and a good bit left in the converter, along will all the other little hiding places. I wouldnt think "chemically" (for lack of better words) that they would work against each other in any way. I just wouldnt be comfortable with it personally.
