I have a pistol grip tool that can hold the toothpaste type tube in it and you can then use any sealant tube you want like a pro.

the GM engine sealant (part no. 12378521) I have is because

1 - it was easy to buy and its the small caulking tube cartridge with precision cut 3mm bead nozzle 5.3 oz for 13 bucks
2 - I have another job - camry 2.4 litre timing case sealing.

Its used for every joint in the modern GM engines, set time is about 20 minutes. I have used toyota 103 FIPG once and it almost resembles this GM sealant except that the toyota one is black.

Reason not to use MB sealant...

1 - spensive
2 - why did it leak in this job? (its not that Im against it - it seals the timing case and sump pretty darn good)

I also can get a tube of Ford branded FIPG (used on the diesel sumps) - the problem is that I would need to destroy the breather covers to remove them if they are bonded with that.
