Help me find my leak

[amagalla]

I have a leak that is allowing water to get under the passenger seat (right side seat for RHD people). I thought it was from the convertible top foam tray, and maybe part of it was. I found a hole in the tray and patched it with a silicone patch and tested it by pouring water in the tray. The drain works fine, the patch doesn't seem to be leaking. There is not as much water getting is a last year (from other sources I've found), but this leak persists. Anyone have any ideas on how to find it?

Thanks for your help.
