Re: Furniture Wax
Yo may want to look into a tougher enamel paint like Cabinet Coat or Advance (the latter by Benjamin Moore). They are both water clean-up but are recent improvements in terms of wear and hardness. Cabinet Coat is a ceramic paint, and is not mixed in dark colors; Advance is an oil/acrylic emulsion, and is mixed in every color.
They would not need any extra protection.
Johnson Wax is much easier to work with than the Minwax finishing wax, but the minwax is very long-lasting; johnson's has to be reapplied yearly.
Remove not the ancient landmark, which your fathers have set.
