Tired of buying new outer coolant seals?
Tired of buying new outer coolant rings when rebuilding a motor?
To keep the coolant rings from expanding, just coat your coolant rings with hylomar and they'll keep their shape. Next time you won't need to keep buying new ones.
I learned this from Carlos Gonzalos.

"HYLOMAR®
This is a non-hardening, high temperature, gasket sealer that we have found excellent for sealing engines. It is easily brushed on the surfaces, and into the grooves, and does not harden, but gets "tacky". This allows re-positioning if necessary. It also can seal gaps between parts up to .010". Withstands temperatures up to 600 degrees F. One tube is normally needed to assemble one engine.
We use it to hold the water seals in the grooves during engine assembly - keeps them there, and they do not swell up as happens with grease or vasoline."

Seems it would burn off the combustion side immediately after assembly. Is there any advantage later?

Pretty sure that is why he referred to only the outer coolant o rings. Same reason that the 'upgraded' o rings are only offered for the inner.
Also, this has more of an application for racers, or guys who are refreshing their motors very often.

Hylomar is an excellent assembly aid for almost anything, from gaskets, to orings, metal seals, whatever. Not only on rotaries but any other engine/equipment. IT is not harmful to sensors, oil supply, water supply, combustion, etc. It washes away soon after being subjected to high temp liquids like coolant and oil, so it should not be used in places that require a very strong seal. I use hylomar for the IRON GROOVE for both coolant seals, but use black rtv for the smooth side rotorhousing surface that the other side of the seals mate to. Especially if reusing rotorhousings, they may have small pits on this mating surface, and if you used only hylomar then it could be washed away soon after startup and coolant could circumvent the seal via the pitting, causing a minor coolant seal leak.
I would rather not take the chance, so I use hylomar on one side and rtv on the other...the rtv dries and stays hard and cannot be washed away. IF you really want to, you can still reuse seals, as they stick to the rtv side upon disassembly, the hylomar does not stretch them.
