> I've used a Loctite with the brush,and if you are inclined to use CA to seal the sides of mushy tips like Elk Masters,or UGLY tips (j/k) like the Sniper,it works great,until the brush starts to get sticky. Rest assured you will get to that point long before you run out of glue,unless you have Joe Blackburn-like work volume.
I squirt some onto a fresh paper towel and use it to seal the surface of linen-based ferrules like Aegis,the Ivorine family,etc,especially if they are really clean to start with,or can't be totally cleaned without RADICAL sanding. On occasion,these materials will show up on even new shafts with crap molded into it,and only an actual cut will take it out,and at times not even then.
It helps me later on,because to a man,every one that comes to me for repairs likes the fact that it's as clean and nice as I can get it when I give it back. Only really dirty/poorly maintained for years leave my hands without looking as close to new as I can get it without sanding all day.
Sometimes,a little dab of CA can help a bad ferrule seam without having to take a cut on it and blend it back flat.
I've never had much of a problem with GETTING bad glue. My problem has been getting great glue and it GOES bad before I use it all. I stopped using the stuff I thought for years was the best out there,Satellite City Hot Stuff/Super T because I'd wind up throwing away half or more of a 17.00 bottle,because of the area I service I just don't get the volume some have. I do more work than both of the other guys that call themselves repairmen in this area combined however,because it's been at least 3 years since I HAD to do a tip for free.
The best choice these days for me is the Gorilla Glue CA in the squeeze tubes,it's a fairly new product so it couldn't have gone bad on the shelf yet,plus it's CHEAP,less than 2 bucks a tube in the packs I get. It's good about going sometimes 5-6 weeks without going bad,and a killer product,no functional failures at all yet if I do my part.
For accelerator,I use an unbranded Bob Smith product in a brown spray bottle. Tommy D.
