Super sticky mastic glue
Super sticky mastic glue that I used for installing my campervav solar panel mounting bracket (QWORK drill free 7 piece set).Product is very sticky and really thick / glutinous and can be a bit hard to squeeze out of the mastic gun. Or rather my grip was getting tired towards the end.Left the solar panel in place with some wieght on it over night and it was solid fixing.
