Just an FYI that might help you. My work sent me to a Loctite seminare. My general ideas about Loctite before this class was usually negative. But now I have a diffrent outlook on the product (when used properly). A couple tips to help you is everything must be clean! And make sure you are using the correct grade/strength. generally blue= normal grade, Red= high strength, green = high grade(bearing retainer). There are hundreads of grades inbetween, this is how I remember. Also, Loctite only bonds to metals that corrode. So Stainless, aluminum won't work. (They make special primers u can spray to work on these metals, but wont work without). As to your original question, it's not neccessary. You can use, I built a 318 with blue on the rod bolts just for the heck of it. And built another sb for a customer (from his request), but usually I use 30w oil. Hope this helps.
