Head Gasket Sealer?

What do you all think of Head Gasket Sealer for Cars? I normally don"t like stop leak stuff.
My wife"s 2005 Buick Rainer has that Orange Anti Freeze in it from the factory, and I hear a lot of bad stuff about that anti freeze that it eats gaskets and it does now her Suv needs anti freeze about once a month.
You can smell it.
I have to add it to the puke tank.
Should I pour some of this stuff in the radiator to get us by for a few years?

Thanks Jeff
 

If you are smelling it I bet that you have an external leak somewhere. my Explorer has an intermittent leak where a sensor goes into the thermostat housing I can't get the sealing ring except with a new $80.00 sensor.
 
I would not use it. Sounds like you don't know where it's leaking. Either pressure test it or have it tested. Stop leak can plug heater cores as well. I don't believe antifreeze will attack gaskets unless it's past it's service limit, then it becomes acidic. Freeze protection is only half the issue with antifreeze. Component protection is the other half.
 
You state you smell antifreeze. Where are smelling it? Inside or outside of car. If inside you may have a heater core leaking. I would pressure test before stop leak.
 
what engine? I had the intake gasket on our 3.8L replaced (orange antifreeze) and in a couple of years started smelling coolent. it looked moist in the area near the tension pully. got a new gasket and the parts man asked it we wanted the little L shaped tube that goes from the intake into the pully housing. Glad we took it. after pulling the intake we found it to be fine but that little tube was leaking.
