Caulk recommendations for bow windows

[Pilot]

This will be my 3rd time re-caulking my top side windows. Eventually the caulk fails (4-5 years in) and leaks into cabin during rain. The design is such that the glass lays flat so water tends to pool around the glass when it rains.

Any recommendations on a good glass caulk? I believe it has to be medium strength and removable. Since its on the exterior it has to white and aesthetically pleasing.

Thanks

i've used Sikaflex 295-UV with good results

Maybe a picture would help. But I am thinking 4200 or similar adhesive/sealant? I know, difficult to remove but it sounds like you're getting some flex in the area which is breaking the caulk seal.
