Super strong
Bonded solar panels to my motorhome fibreglass roof. This stuff is seriously strong. You get what you pay for!

Works great BUT must be stored correctly
Used this to repair some Waders with some tiny holes in, works great dries fast and with some permanent marker over the top you cant notice it. Only gripe I have which is pretty self explanatory is once opened it does go off very quickly in the tube rendering it useless unless you cut the tube to get to the not dried out sealant. Would recommend decanting into a air tight tub to prevent this.

Excellent
Used this to attach silicone flashing to a cement panel and the cement panel onto a caravan roof in the rain. Not one leak.
