Hi Rich,
Loctite 542 is a dark red, almost brown, liquid. It's big advantage is that it is rated at 300 deg.(F) It's big disadvantage is that it's not cheap, currently around $16.00 for a small bottle.
It's never failed me though. As long as the threads are clean, and you let it set overnight. I was turned on to Loctite 542 by Keith Appleton, who has a youtube channel devoted to fixing/restoring old steam engines.

this stuff I picked up says 400F (or I think it did). So far no problems at all with Permatex and I really steamed the engine up too.
Hmm... I might have to try some of that stuff. [ Guests cannot view attachments ]
I got my Nickel over Steel rivets in and installed today - job done. They could be a hair shorter but I got them snugged down.
Hanson Rivet & Supply Co. - Cost Zero as the fellow just sent me "Samples" of 10 (they only sell in 100 or greater). I also got C4's (Truss) but as he said I wouldn't like them as the head was to wide.

The little Tonka custom rivet tool I got off eBay worked like a charm too. Anyone that does this too, happy to loan it out. I even went ahead and bought set of screws that let me change the rivet tool heads out.
Excellent job, Rich. Just like factory!
