Water leaks

[Lippyp]

I've resealed my drip rail and I've seam sealed all my new repairs (kick panel, floor patch and rockers yet today I still found a little bit of water in my footwells (the carpet is out at the moment.) Where else is this likely to be getting in? Are there any common problem areas, i guess it could be the screen rubber leaking, the firewall seems solid but are there any areas under the cowl likely to leak? Obviously number one plan is to get her under some cover but I do want to sort these leaks before I fit my new carpet and it rains a lot here!

Thanks guys.
