Used for mounting Motorhome solar panels.
I used this to mount solar panels to my motorhome roof. Great stuff and extremely secure bond using aluminium angle 3mm thick 50mm x 50mm bolted to the solar panel. No bolts used to attach to the roof just the adhesive. The panels were fitted 8 months ago and I regularly check the panels to ensure they're still secure - so far so good!
