Testors Cement Glue
I would highly recommend Testors Cement Glue to every modeler. However, there are a few drawbacks. One of these drawbacks is how, without applying much if any pressure to the tube, the glue comes pouring out, possibly landing on an inconvenient spot on your model. The caps provided with this kit, though, do help a little bit with this problem. If you are going to to buy cement glue, I highly recommend getting the caps with them, as it helps greatly with gluing small parts. One drawback with the caps is that the glue will dry inside the caps, and eventually will clog them. (Hint: For maximum use of the caps, I suggest buying small pins to poke holes through the partially dried glue in the caps.) Also, this glue has a strong odor. Other than that, I personally like this glue much better than Testors Non-Toxic Cement Glue, because it seems that this glue dries faster, a quality that I find especially helpful when having to hold two pieces together till the glue dries. In spite of its drawbacks, I would still highly recommend this glue.
Hard to control the squeeze
Actually squeezing this stuff out requires a little bit of a learning curve. Sometimes it seems like the stuff is under pressure even without squeezing and will start squirting out even without any intent. This could be dangerous of a blob lands where you don't want it. Here's a pro tip. Try not to hold the tube perpendicular to the floor (straight down) when gluing. Use a more shallow angle and that will help minimize the risk of over-application. I've found that the little included tips here help mitigate that quite a bit but also that they're somewhat difficult to keep on the tube. But still. I've been using Testors cement for as long as I can remember. And will continue to use it.. well.. forever. :)
Testors Plastic Cement Value Pack
This is plastic cement that comes in a tube, its bonding is better than non toxic glue. It is very thick, but the tube tends to flow out more glue than what is needed. The glue melts most plastic (except for ABS). Preferably, I would pit some on a cardboard piece and then apply the glue with a toothpick. The value pack allows for tips for new users. You also get more for your money ;)
