I tried something from HD, and it should have worked, but couldn't fasten it.
It looked promising, too!
But, it kept shifting. So, I pulled the door jambs off
I'm gluing 1/4" poplar strips that will be behind the door jamb
When the glue dries sufficiently, I will put the door jambs back on and have 1/4" to put weatherstripping in. Hope it works!
