Blown head gasket

Has anyone used or heard of engine repair pellets to seal a crack? Or has anyone used Heal-a-Seal to repair blown head gasket? I found this on the internet and would like anyone who has used this to give me some feedback on it. thanks

I don’t think so, just a bunch of whatever

Just someone trying to get a few $$ from you with a scam that you wish would work.

This guy used a lot of radiator stuff and sealed a cracked head but the radiator got plugged up badly. It is usually a losing effort. You want the car to run after you “fix” it.
