Which Loc-Tite?

This should be a simple question for you smithy experts:

I have a couple S&W revolvers where the screw that holds the cylinder latch likes to come loose.

Which Loc-Tite do I use to keep them from vibrating loose?

This is internet talk:
Elmer’s glue is polyvinylacetate and polyvinyl alcohol
Blue Loctite is Polyglycol dimethacrylate and Polyglycol oleate

Greek to me.

Heat transfer tip

Loc-tite is great stuff. Handy as a pocket on a shirt.

The green wicking stuff is a double edged sword, use caution and apply very sparingly. It is very strong. It's also really really good at wicking in where you might not want it to.

When it's time to disassemble.
The key is to only heat the fastener. I have found the best way is to use a "sacrificial" driver bit. Heat the driver while inserted in to the offending screw.

A soldering iron also works well. Your nose knows! Loc-tite has a sweet odor, should be able to smell it when it is hot enough to let go.

I have had great results even when the assembly is painted by using the heat transfer method.
