Squealing front brakes
I have a 2016 335GT M Sport and the front brakes are squealing since forever... the spray works for a few days but the squeal is always back. Anyone else with this problem? I don't suspect wear since it has been doing it almost immediately when the car was new. It just drives me insane to require to spray the rotor with anti squeal every week.

If you're handy and have the time, you can try filing the edges of the brake pad to chamfer it a bit. Squealing is usually caused by the back edge (or bottom edge) of the pad grabbing prior to the rest of the pad, causing it to vibrate.
Before doing anything, try doing some high speed to slow speed braking actions to scrub the surface of the rotor and pad. The goo on the back of the pad can help, but the sprays for the rotors are usually useless.
