building a sterilite 1960 rack...1/2" or 5/8" plywood?

see if you can find a company that supplies XPVC and if they make sheets.

4ftx8ft sheets i found at a company was $59 per sheet. I may buy some and make my own to make racks lighter.

Wow, thats an awesome price! I would definitely go that route if I could find it that cheap.
