Does Sea Foam Spray effect my catalytic converter? [SOLVED]

I have a 1986 Ford 4.9L. Would a Sea Foam Spray treatment have any effect on the exhaust system’s catalytic converter?

Thanks for the question James. We get a lot of questions on catalytic converters. Sea Foam engine treatment product have no relationship with how a catalytic converter works. Sea Foam and Sea Foam Spray are vaporized in the chamber, so there’s no downstream effect.
