as usually you are amazing masha allah
hey Syed!
I wouldnt be too confident on the tank! 0,5 is quite a lot and keeping in mind that its 0,5 with a brace plus the fact that the silicone job it doesn't look so sleek ( i am afraid of week points such as air bubbles etc) I would like to suggest that you add another set of braces below the existing top brace!
Dont want to spoil the fun buddy but mine bows 0,2 and its rimless
Just my 2 cents anyways
