Default Cam sprocket bolts

I was just reading the Loctite site and they are suggesting using their top strength RED 272 threadlocker on cam sprocket bolts.. Writeup says you will have to use heat to remove the bolts once applied. I was just gonna use the blue 243 threadlocker to bolt on the cam sprocket. Just wondering if anybody has had any experience with these products and is that RED 272 that dang good as to have to use heat in order to remove it.

Thanks

I found this that should answer your question.


WHICH LOCTITE TO USE


--------------------------------------------------------------------------------

The below information was taken from the Loctite Industrial Product Guide and as you can see all of the temp. ranges are -65 to 300 degrees F., except 272 red which is up to 450 degrees. The cure times vary except they all require 24 hours to cure fully. Hope you can save some space with this added information. Loctite also has Gasketing material, Thread sealing for fluid fittings, Retaining Compound and Bonding Adhesives. Later!
