I'm just guessing that the Tamiya stuff is similar to the Loctite gel in the plastic twist push-up applicator. Done right, the 242 glues things on much tighter.
I even glue my pinions to my motor shafts. I use nothing on the setscrew.
I'm sure the gel works, but not for me in RC applications. I've had great luck with the gel locktite blue on Rifle stocks.
I'll stick to the thin messy 242. Besides it tastes delicious. (don't drink it)
