RTFM - Enchantment bonuses are the "Shape & Material" (5e) or "Form & Effect" (4e) bonuses.
They are mentioned in the description of the Lab system for creating enchanted devices, and there's a table of things/substances and the bonuses they give, together with the areas to which those bonuses apply.
Now - go back and read the Lab chapter, and look down the F&E table in your free copy of 4e!
Using the "Mortals can sell/trade magick items" loophole in the Code, I would suspect that an enchanted makeup kit w/ Re-Te/Aq that would keep the rain and mud off you would be very popular amongst the nobles.
