Irontite All Weather Seal, Pour and Go to stop leaks
[468-9130-16]

I recently rebuilt an Old School1977 Dodge BB 400 motor as stock and per hot rodders, Model T owners etc.., this is a must to use product on any rebuilt / refurbished motor to protect both the cast iron heads and block. Rvs / Motor Homes by design create allot of extra heat especially when towing or going up hill. Per they're advice I'm doing it as a preventive measure. I'm sure the results will be Great after I hit the mountains and back.
