what would happen if I used radiator stop leak for trail emergencies? will it gum up the works? in auto systems it is added to extend water pump seal life, any thoughts? as you may have guessed this is my first water cooled.

Sent dented radiator with leak to mylars for repair, reinstalled and had very small leak after reinstall only when running. Wouldnt even show up with 40lb pressure test. Called Mylers, recommended "pinch" of alumaseal. Worked immediately.
