Initially: I got it on the recommendation of a Borg Warner engineer who has used it on 'everything' for a decade. Also others I know who work/ed in aviation and have used it only as stated with zero failures/leaks.

For me I tested it only recently to ~1100deg C EGT on a T4 flanged set up that was prone to EATING gaskets, problem solved so far.

This came about due to me doing research on alternative sealing methods (spent 2 months on it with various people around the world) and wanting to go away from the use of gaskets on normal bolted flanged turbos, but also eliminating leaks on V'bands... I have other systems that I will/am testing such as Nickle based wire in a groove machined into the turbo flange, but so far that system is not needed with the use of this product

Done this and it works well, the only downside is the setup time for machining. Until we discovered even this wasn't necessary.

We stopped using gaskets on the drift cars a couple of years ago, and stopped having problems too. No paste either. Just flat mating faces, and most importantly, black cap screws in place of studs - less stretch.

Try the paste mate, your turbo supplier got me onto it as NOTHING is ever perfectly flat, I know being a machinist by trade
p.s. he is my supplier now, real top bloke!
p.p.s G8 or higher BOLTS and nuts clamping the two flanges are the ONLY way to do it, you see this on OLD 1970's turbo cars too!

Marmon clamps. We used those and metal seals inside the high temp bleed air systems on supers.
