Great website, first off...

I just got started modeling again after a very long time. A couple basic questions:

1. What is the best technique to use to cement very small parts together? I purchased a liquid plastic cement with the metal precision applicator (which is nice), but even that dispenses too much glue for some of the tiny pieces that need glue applied to a spot about the size of a large pin head..How do I do this?

2. How do you remove excess glue from the model when you mess up or smear glue by accident on the surface of the model?

Thank you!
