Last weekend I visited my two moms over in upstate NY. They own a turn of the century farmhouse that they've been slowly restoring. Part of the process has been stripping oh...100 years of paint off of the door moldings and fireplace mantel. The mid-project results are beautiful - at some point the house was painted teal and the color has come up through the sanding. This is real age - not anything you could fake.
Personally, I think they should keep them like this, but the moms wouldn't go for it.
