Thread: DPT Suppressor seized up

No comment on whether a nickel anti-seize would actually cause galvanic corrosion in this application - I haven't looked into it to make my own mind up - but according to CRC for aluminum you want a zinc anti-seize. From their website:

Zinc Grade is for aluminum threaded components. Used to prevent seizing during assembly or disassembly of threaded or unthreaded components fabricated from aluminum or its alloys, engaged with components fabricated from similar or dissimilar metals. It is also intended to provide corrosion protection to the metal surfaces. This type is typically used in airplane manufacturing.

Currently on clearance pricing at NZSafetyBlackwoods for only $50.49 for a 1lb can. Should be enough to keep your suppressor from seizing for a millennia or two Or maybe someone wants to sell it on the forum at $5 an ounce?
