I know what you're thinking: "Kenny, you just got done telling me not to let my airtight home be filled with VOCs, and now you're telling me to bring crusty old building products into my house and leave the old lead paint on them for charm?"
Yes, but there's one more step. If you want to safely coexist with surfaces that may be covered in lead paint (and any painted surface from before 1978 should be considered a risk), you can encapsulate the lead by using a product like this one from Nansulate. It has a very low level of sheen, so you won't even know it's there. And you can get that rustic look without endangering your family.
