Plastiweld (1)

This is the best plastic cement I have used. (I really hate the tube stuff.) Use sparingly, and you can build a real nice plastic model. It wicks in like CA, and quickly makes a strong bond. A favorite use of mine is for building rail guides for model rockets out of ABS Plastruct H columns, as well as rectangular and square tubes. I just cut my pieces to size and shape, hold them together and wick in the cement. Done! Just remember to keep the lid on tight, or it will evaporate before you know it. Also, don't put it on too heavily, it runs like water and will get all over your work.
