Tubbing the front / inner skirts

I'd like to know what everyone that's tubbed their front (or even rear) does to make the tubs more functional and come out to the fenders/bedsides to keep shit from going in places it shouldn't...

Is there some universal rubber/plastic that can be attached to the tub that would press up to the inside of the fenders that anyone knows about?

I know I'll never get "factory" protection, but I drive mine everywhere and would like to try to keep salt and debris from killing my sheet metal...

the only tubs i do to the bedsides are on Blazers, but thats needed or the interior walls will fill up with crap behind the panels hah.

so what do you do? just constantly clean in the door jambs up front and hope for the best?

I'm not AS concerned w/ the bedsides since they were somewhat open to the elements to begin with, but that door jamb area seems to be getting hammered with crap now...
