Got the Brax Exvibration send over ARS24. The box was well packed and glued at the opening additionally taped. Got my doors insulated with Alubutyl and made it a layer Brax. Have the paste processed by plastic spatula and it can be distributed fairly, not very good but that was clearly because it is a paste. I guess with the gun would be gone definitely clean, but it was indeed that way. Giant Erfreunis came when I assembled the door, one that something was fresh there hatn absolutely no smell of the paste as it is solvent-free, so I did not realize there the smell ago.
Unfortunately I have no comparison from the sound since I directly before another layer Alubutyl did, so I can not evaluate the Brax alone.
But now, in collaboration with the Butyl I have to say the sound has improved a lot, did not think the insulation could make as much.
1stern I have withdrawn, as it partly a fiddly job was with the spatula
