Ive been using it for years on my cars, trucks and motorcyle exhaust. they built race engines and told me it has a higher heat tolorance then anti-seiz.

I just pulled off my motorcycle exhaust after 5 years that had aluminium heads and stainless studs and nuts and they came off with ease was it malox dono but it still had it on the threads after 5 years.

yep Maalox or Milk of Magnesia have been used in high heat situations for a long time. put it on the bolt and let it dry then break off the excess
