did masonite ever contain asbestos even the real old stuff
None that I know of!
no… made of the same stuff that tentest is made of… only tighter squishing…( goota love that word)
It is really just a hard fiberboard.
No, it was made of wood fibers, resins and wax. There was a class action lawsuit against the Masonite corp on their product but its time limits has expired. View some info on it here
