Instructional Videos: TAP Plastics

I found these while searching up tutorials, and found them very useful. They are a company trying to sell their product, yes, but they are sincere at it. I lol'ed at one part, where they say you can use their several-hundred-dollar vacumm to remove air from resin, or you can use a plastic cup.

If anybody else finds more, post them!

EDIT: Same videos, in youtube:
