Header exhaust leak - help!

Guys I hate to report this but I STILL have a leak. Ended up getting my headers back from the machine shop, straight as an arrow.. got the Percy's and installed them. After all said and done the car sat until tonight. The leak is I'd say 75% gone but still enough to twist my tittie.

I've heard some guys use red or orange rtv but I picked up this stuff called quick steel, supposedly withstands up to 2400f. Not sure if I should try this or give the REMFLEX gaskets a go.

Video coming soon.
