I am going to go with either MDF or Particleboard 4 layers laminated with a final 1/4 replaceable layer of hardy board for my workbench top. The over all dimensions will be 40x96. I have read conflicting information between which would be a better product. To fasten to the top to my steel legs, I will countersink bolts that will be hidden by the hardy board. So this leaves me with 2 questions

1. MDF or Particleboard
2. What kind of glue should I use for lamination


Thanks!
