Rough-In Tools?

Any long time subscribers/customers can tell you coming up with new ideas to make your lives easier is my favorite part of my job, while marketing to you with these magnificent emails falls more towards the bottom of the list.

I've got an idea for a plug, in fact it is part of my patent for Vent Caps, that would seal the a/c boot itself from the inside.  It would easily seal any lines coming in, but my preferred iteration wouldn't seal the boot itself.  I know they're SUPPOSED to be sealed and even caulked to the drywall, but I'm sure not too many builders are doing it.  So here's my question:

Would a quick and easy seal that literally plugs the boot itself be something that you would use, or would it need to seal the whole boot?  Please enter a quick answer in the form below.
