How and with what? I have not done anything really yet just re attached a small hose from the heater box and it has been raining heavily,so I go out and look and the floorboard is dry as a bone! Go figure. I assume you used silicone, my seal actually looks great if you can tell by looking. This is just more annoying than being an actual problem but I would like to get started on the interior and keep it dry after. Thanks for the reply.
