Radiator question

[g300d]

My 04 X5 3.0 is currently at 42t miles or so.

Looking under the hood, I see some water at the radiator core/end tank seam near the upper radiator hose neck.

I cleaned the area and drove for a bit and it was wet again when I checked it after the drive. There were no cracks. It looks like it's coming from the seam.

I come across this video by the guys at BMP. They say it is a common leak point in BMW radiators caused by heat cycling/flexing of the radiator causing the crimp to loosen.

Seeing that it looks like I have this exact same problem, I am thinking of having the area re-crimped. I have a good radiator shop nearby who has repaired similarly crimped Mercedes radiators for me in the past and thinks this is worth a shot.

What do you guys think?

Will post pics of leak and link to BMP Youtube vid later, internet is kinda slow here.
