SONOSAILOR & DEL:
Thanks to DEL for pointing out the potential for "liquifaction"
on some of these products.
Upon revisting my earlier posting
, I understand why "Binacle" offered up "Starbright Anti-Sieze". It's closely related to the 'No-Corrode', 'No-Alox', 'Penetrox', and 'Ox-Guard' products I recommended; all of which could be subject to thinning out at higher temperatures.
As DEL suggested, try the 3M Sealers
, or perhaps Epoxy Resin
My apologies for my earlier ill concieved advice - and thanks to DEL for thinking it through.
