How I fixed my leaky G37 roof! (Mostly haha)

Hey I know this is an old thread I'm just wondering if you ever got the leak completely fixed. I'm looking at buying a 2010 g37 that has a leak on both sides in the back. I'm told it's really expensive to fix. Should this be a reason not to buy the car? It's got 60k miles on it and in very good condition.

We've had a few heavy rains and I've noticed my headliner has some stains on the driver's side above and behind the rear window. Last night, I came outside after a few at a bar and it had been raining - not particularly hard - and the headliner was wet. I read through your post and it seems to me that the back portion of the seal that is attached to the middle panel is likely the culprit. Rather than partially open the roof and apply the "normal" clear Permatex RTV sealant, I used some "flowable" clear Permatex along the back edge of that seal along the entire roof. It comes in a small tube and I used a large needle to put a hole in the screw-on spout to get a small bead along that back edge. It's not as thick as the regular sealant and settled nicely in between the seal and the roof. I know that portion of the seal is attached to the middle panel so there should be no movement in the sealant once cured. There's no rain in the forecast until this weekend so we'll have to wait to see if it works. My guess is that it will be a temporary fix at best, but who knows? I'll follow up on this post later.
Thanks.
Thanks.

A big warning for anybody doing this.
NEVER leave your roof in the partially open position for more than 15 minutes.
If you do, you are in for a a whole heap of trouble, trust me, I have been there, it isn't something you would want to fix. Mentioned on page 271 of the FSM in the RF section by the way.
