User-Friendly CA does have some trades to consider. Probably the most frustrating is variable set time. I've tried several brands; some take almost as long to set up as alaphatics. Currently using B&B Specialties Super-Gold thin with pretty good results including fairly quick set up. Anchor Bond odorless sets up really slow. Hot Stuff UFO lies somewhere in between. One problem I have run into lately is finding user-friendly CA in my local hobby shops. They complain that the shelf life is too short for them to keep in stock. I have found that it does gel a lot quicker than the regular CA I resort to when nothing else will do.

As for relative strengths, I haven't conducted any tests that would produce an opinion one way or the other. When it works, the U-F seems to do the job.

By the way, I have used fans, even limited my use of regular CA to outdoors. As I said, even the slightest whiff sets me off.

Would like to know what User-Friendly brands get high marks from the builders.
