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.

Recomendable
Lo utilice para sellar los radios de un par de rines de motocicleta, pero pues talvez no lo hice de manera adecuada porque no sello al 100%, el producto funciona tal cual la descripción, quizá para otro tipo de trabajo funcionará de manera correcta.

Super bond
Stuff is amazing. Super strong bond. Glued the pedestals in my boat for the seats to bolt onto. They will never move now.
