What year was the last year they made lead paint in the USA?
Actually paints that contain lead are still manufactured, just depends on the purpose of the paint.
Lead in household paints was outlawed in the late '70's.
I believe it was 78 or 79 when they outlawed them.
The manufacture of lead paint for residential use was outlawed in 1978. Here is a link to the EPA website outlining the new lead laws for renovating and painting in homes. http://www.epa.gov/lead/pubs/rrpfactsheet2008.htm
