Glassing, Lams and Laps

So as I’m reading about laminating and laps there are terms and processes being thrown out that I’m completely clueless on. I was curious if you all can help me out. When people are talking about laps they talk about “Pinlines”. What are these? What do they do? Taping - When people are talking about doing lams, they say that they tape down and then “Slice” the tape to cut the laps. What exactly is meant by this? Does anyone have an article orl ink to an article on how exactly to do this. Lapping methods - Is there more then one? What are they? Which are best? Where can I go to learn. Laminating - when doing the lam coat and you don’t use wax, what happens if you are less than perfect and need to sand? Is there a chance to do so and if so, how? What problems occur. Double Glassing - When doing double glass for the deck, do you do it all at once (i.e. Run both layers of glass then pour your lam resin) or do you lam one layer then lay the second glass and lay that layer? Squeege - How hard should the pressure be? What are the signs of too hard and/or too soft? Forgive my ignorance guys and girls, I’m trying to grasp all this knowledge.
