Do I need to assemble this, or does it ship ready to use?

Ships as a single unit — set it in place and start working. No assembly required.

Will this bench hold heavy engine blocks or transmissions?

Built for professional shop use with solid construction. Test the weight load against your specific project before committing critical components to the top surface.

What's the best way to protect the work surface from spills and scratches?

Wipe down after each use and avoid leaving harsh chemicals sitting on the top for extended periods. A shop towel and degreaser will keep it ready for the next job.
