I'm pretty sure it should be installed with sealant - 3m makes good quality weatherstrip adhesive.

Coincidentally, I've had the exact same issue. Unfortunately I didn't catch it until I started getting some rust in the rear fenders just behind the wheel arch. I POR-15'd the entire trunk bottom due to some other rust, but didn't get into the crevice where the wheel arch meets the fender. I just got a welder to do the repairs, but need a ton of practice first. In the meantime until I can afford OEM seals, I added some universal automotive weatherstripping (From the big blue store) to the bottom edge of the trunk lid. It seems to have helped make a good seal, in that it's more difficult to shut the trunk now, but I haven't had the car in the rain to see if there's any more water ingress.

I'd strongly suggest you rustproof the trunk floors and side wells before you run into more problems, like I did. A bit more paint would have saved me a ton of work and money for paint blending.
