Used it on an antique tractor block, sealed it up very nicely. No noticeable oil in coolant, no coolant in cylinders, follow directions works good

Works fantastic on cracked aluminum blocks. Haven't had any issues in 6 weeks and brought my 2000 Pontiac Bonneville back to life. Zero antifreeze in my oil since
