TY CP, that makes sense. I appreciate your input!

That makes sense. Do you know if anybody has ever tired "pressure forming as in you push air pressure to for something like the exact opposite of creating a vacuum? if you were to place say an object on the bottom of a box, and then place the plastic/acrylic, and then apply air pressure above the acrylic? I know that may sounds crazy, Im just curious why they create a vacuum below the mold instead of applying only air pressure above it. Any ideas?

So the primary reason for pressure forming is for fine details. correct?

Just out of curiosity, does anybody know why they use vacuum forming for spa shell molds instead of pressure forming?

Thats a good lookin tub! Is it difficult to use the spa cover lift under the enclosure at all?
