I just traded jks and took the Spidertraxs off the old one, easy and I didn't need heat. They were on for 14 months, I checked them regularly.

 

I've always used Permatex Red whenever I've needed threadlocker and never had a problem getting it off without heat. It definitely does the job, but isn't "permanent" in my experience. I've never tried actual Loctite-branded threadlocker.

I'll be removing my Spydertrax spacers next week when my 35's arrive. Hopefully no issues...
