Default What's the best Thread-Lock brand

I'm looking for some feedback on what others have found to be good thread locking compound. I'm currently using "Great Planes" commonly blue stuff but it doesn't seem to be that great. Its the removable formula which is what should be used I suppose.
Also, what a good idea to keep CVD boots in place. I have a Mayhem that I use on a large oval and with new cvd's I see the boots will slide off the yolk at high rpm.
Thanks

Loctite 243. Its important to degrease parts before thread locking, otherwise the thread lock will not be as effective.

I used to use a small cable tie to hold the central cvd boots in place on my mbx6.

Permatex or Locktite. Both available at Napa.

The Gel pens are nice as well. That's the threadlock that is preapplied and dry on some aftermarket parts. Usually it works well even if the screw gets removed a few times.

-Blue is the regular stuff
-Red is stronger, often requiring a butane torch to heat ther screw up for removal. Only for isolated metal to metal, not something near plastic usually.
-green is usually penatrating. For linkages. Adjust link, then apply to turnbuckle links. It'll soak in and lock up the threads. (not common in RC cars, handy in airplanes though)

You would think much of the blue would be the same regardless of the manufacture but this isn't true. I've used a lot of threadlocker just not so much on RC but the brand I have now is just not consistent even after shaking. I think the trick is some are formulated for larger threads.
I found this http://cgi.ebay.com/ws/eBayISAPI.dll...284#vi-content but is too expensive. I think the Loctite 243 mentioned by Chris-s is what I'll go get. I actually just found the 222MS much cheaper.

Lock-Tite 243.

I use Purple for everything but the engine mount.

I use blue for the engine mount.

So your saying you use the 222? It's purple like you mentioned and 243 is the blue. I'm now leaning towards using 222 and calling around now. I read another Ad for it and stated its good for small set screws under 1/4" and prevents backing out(loosening) under load or vibration.
All medium thread lock will do the job to a degree but it seems the 222 is a little more to 100% since it's for smaller diameter screws.
I also found this thread thread lock!!!! I guess I didn't look good enough. Thank for all the input it really helped.

When I worked for an electronic mfg. we had 4 colours. purple, blue, red, and clear. I do not remember the numbers but I do know that is was all lock-tite. I would use the purple and blue on my RC stuff and i never had any problems.

The colors denote the strength:
Purple= Mild
Blue=medium
red=Strong ( must heat to remove )
Clear=Permanent ( Like glue... do not use for RC!!)

I use a small piece of heatshrink over my CVD boots to help hold them on. Haven't had a boot slide off yet. It should be noted that the "yolk" as you call it, where the boot is held in place, is tapered down on my axles. There is a similar reduction in size on the center drive shafts as well. This ALSO helps keeps these boots on (this in on a Hot Bodies D8 buggy).

Default confused on threadlocks?

most people get a little confused about thread locks - you tend to get what you pay for and the manufacturers tend to over due it when it comes to choices

Ive always used Team Associated with great success. As someone else said earlier its important to degrease before use.
