What do I need to assemble this, and does it come with fasteners?

The bench ships fully assembled — unbox it and position it. No additional hardware or tools needed for setup.

Can I bolt this down permanently to the floor?

The bench is designed as a standalone unit. If you want to secure it to concrete or wood, drill your own anchor points based on your garage floor type and local code.

Is the top surface treated, or will it rust if I spill coolant or brake fluid on it?

The work surface is hard panel construction and can handle typical garage fluids and spills without damage. Wipe it down after use to keep it clean; no special sealing or maintenance required.
