I would like to:

• Remain as close as possible to the color of the table.
• Remain as close as possible to the powdery RH look.
• Completely protect against water and oil spills/marks.

The three contenders are:

• Rubio Monocoat Oil Plus 2C-A, in Pure
• Tung Oil
• Modern Masters Dead Flat Varnish

The two tables I ordered are:

• RH Flatiron Bar (https://www.restorationhardware.com/catalog/product/product.jsp?productId=prod2270005)
• RH 1900s Boulangerie Rectangular Extension Dining Table, in Natural (https://www.restorationhardware.com/catalog/product/product.jsp?productId=prod370026&categoryId=search)

I've read a ton in regard to Rubio Monocoat Oil, sounds very promising and will most likely be my choice if there isn't a sufficient amount of support for the other two. Just found out about Modern Masters Dead Flat Varnish a few moments ago. A lady reviewed it stating that it did not alter the RH powdery finish at all.

Thank you all in advance for your help!
