  • Great product

    I used the white master seal to bond a solar panel to my T2 pop top roof. The sealant is very workable and controllable, I used a spreader to move it around the panel and leave some rainwater drainage channels and attached it some 5 minutes later. I then ran a thin bead around the outside edge to give a tidy finish. It is very adhesive and went off about an hour later but because I had a small curve in the roof I weighted the panel down for 24 hours. Very happy with the result, another great item from JK.
