It ( Superweld ) is not as strong of a bond as the CRL but it is easier to break free and even remove from optics with a strong thumbnail, so for temporary makeshift arrangements it's just right, but for a permanent build I use the CRL.
The CRL is strong and works well but it can have a very thin surface tack that fully cures after a day or so, I haven't noticed any out-gassing or optics contamination from it, but I have been wanting to try this one.
When you edit a post that has in the string it comes back as an emoji and doesn't work, these strings are so long they inevitability contain that sequence, so rather than recopy each string and repost it, I just made 3 posts, it's not that often that I post in this thread and the site is not all that busy, so there's no need to do it the hard way just to avoid a bit of childish prattle from some old hippy socialist who's unhappy about being wrong all the time and looking for any chance to snipe at his intellectual superior.
