Hi Scotty, I recently flushed my radiator, put in 2 gallons of water along with steel seal in the reserve tank and let it run for 30 minutes. Shut it off, added Prestone coolant and drove it mildly, it's still overheating. Did I do something wrong?
Keep up the good work.

Did I do something wrong?
I guess in the sense that you gambled with a product claiming miracles and it just didn't work out. Those kind of "sealers" are very hit or miss and are temporary even if they do work. The only way you can really fix a blown head gasket is to replace it. Scotty has stated his preference for the Bar's Leaks head gasket product if one wants to roll the dice with that type of thing.
Here is another site member's recent experience with sealers where it appears the problem was allowed to continue too long:
