And aluminum wiring was going to replace copper wiring, and polybutylene
pipes were going to replace copper water pipes. And fire retardant plywood
was the ticket for townhouse roofs. And there's no need to put cinderblock
under stucco, just nail the wire to the 2 x 4 frame and spray it on. Of

Stay away from stuff when it's "new". Stick with whats been around a while
and proven itself. After it's been field tested on every one else and proven
to work, OK.              Jeff S. ( who once owned a house with polybutylene
