I have had the glue down mounts on my AXIS since the first part of 2017, I get on the roof every year with the Dicor to check all joints, the glue Renogy wanted me to use is called Sikaflex an I had to find a special primer from a local construction supply dealer, we get the Santa Ann winds in Southern California and they can take an awning off a rig going through the mountains in a heart beat, if ever they loosen up I will have the option to just add some screws but they assured me if installed correctly they will never come off, I have 4 of the 100 watt panels and they use 6 mounts per panel
