The panels came quickly and all were in great condition.  The panels are majorly thick but they are substantial enough for the job and some manipulation and bending to maneuver into spaces.  I have installed it with no skill or education and it goes pretty quickly.  I'm doing a huge space 600 sq. ft garage ceiling and I can't wait to get it done and post some pics.  You can spray paint but I'm going with a simple black and white scheme and these need no coating.  Great remedy for old discolored drop ceiling panels!
