I'm really happy with these from Amazon :

Firm so no chance of bottoming out on the drywall or "wearing out" like weather stripping will, and a good squish so it won't scuff paint or stress the door lip. The adhesive is super good, I'm sure it will never come off no matter how hard I try.
Comes in a pack of 4, I used 2 per door lined up side by side to make a nice wide target area so I don't have to perfectly park to get alignment.
