Yes, but for best results, make sure the edges that are to be glued together are Relatively free of Oxidized Lead Surface.
Scrape off the dark lead "skin" with a dull xacto blade. Not so much to mess up any seams or fits, but just enough to "silver it up" An emory board would work even better.
The most common problem is over application. The idea is to have enough to exactly fill the void between parts. I normally use:
A coffee straw
or robust sort of toothpick
(not the flat kind)
or Wooden Match
or a Q-tip
to apply epoxy with. they are disposable. The Q-tip, (with or without the fuzz) is probably best for this. Medical Culture Swabs, even better. Equally important to judging amounts of epoxy is application control.
YOu want a 50/50 mix of elements A and B. the wrong mix can cause it to never cure, and also be really nasty and sticky, or it can cure but will be a brittle hold, and will break. You dont need to be micro exact, +/- 5-10% should be ok.
When setting let gravity do the work. Let a little part sit on a big part, rather than taping them up. try to set them in as close the final position as possible, on a nice level surface.
During part of the curing process, the epoxy can drip as its chemistry changes. This drip can happen so slow , you'll see it the next morning.
2- Ton should set to handle in 30 minutes, and ok to paint in 24 hours. Best Bet is to let it sit for 24 hours.
DONT:
Try to wipe off a glob if it gets on the ship. best bet is to wait for it to set and sand or cut it off. On the first day after curing, it should chip off easy. If you try to wipe it off beforehand, the epoxy will pull fibers from wahtever kind of cloth you are using and get nas-T.
DONT:
Use epoxy over a year old, it will never cure. It will be yellow, sticky, and never loose the epoxy smell.
DONT:
use the epoxy you have mixed when it starts to get sort of stiff and tacky, the bond will be weak.
If you want an easier go, I recommend Pacer "Zap-A-Gap" CA+, in the flourescent Green tube. This is a fast acting, gap filling, superglue that is easy to control, and incredibly versatile. The good thing about it is that it can be cracked off easier than epoxy if you want to repaingt or change the model in the future. The other benefit is that it sets in 30 seconds, and Is much easier to control than off the shelf superglue. You can get in online or at hobby stores.
The other recommendation is try stuff out. Both methods can be redone with no real trouble, but better overall results can be had with better control over the application of the glue. There is a small practice curve to application, but when you get good at it, you can really see it.
