The best glue

It's all a matter of preference. for small parts or sub-assemblies that aren't very visible, I use the dreaded tube glue. As long as you don't let the strings of cement go everywhere, you'll be fine. for large pieces, it depends on the application. And for small fiddly or large and fragile joints, go with superglue, that or even epoxy. For clear parts, I always use either Tacky craft glue, or 5-min epoxy.

Welcome back to the hobby, Tom,

I primarily use 3 glues on any given subject:

Tenax 7R a liquid plastic "welder" for fuse. and wing seams

Model Master liquid cement - thicker than tenax, not as thick as their tube glue, longer working time. Also the bottle has a metal needle applicator built in.

CA - for filling seams and whatnot, get both thin and thick...

Welcome back to our world!  I was like you when I returned and I only used the tube glue.  Too messy!  Like Killjoy, I use zap-a-gap as my CA for resin and metal PE parts.  I have been using the liquid cement from Testor but recently switched to Tamiya Extra Thin liquid cement because I like its larger base so it won't be spilled again as it has happened to me twice in a year. 

There are so many good choices of glues out there... I have about six or seven different glues at my workspace and all of them serve different purposes. 

I prefer Zap-a-gap's 'Plasti-zap.'  It is a CA formulated for plastics, and it is thicker than tenax.  I can apply it with anything from the tip on the bottle to a toothpick or a small paint brush.

I get it at my LHS, but this shows you the product.
