Foam footwells

What do you guys do to keep the water out when you fill the storage compartments up with expanding foam? I was thinking just smear some silicon sealant over the end but wanted to get your thoughts before doing this.

Thanks

can you glue the cap back in place?

Nah well thats the thing. I couldn't be bothered painting the purple caps to match my new scheme, so I am just filling it with foam and when the side cusions are re-apholstered they will just cover over the hole. I just don'tlike the idea of water getting into the foam.

You could try 3m 5200 sealer thats what every one on pwc uses to hold and seal in there footholds.
