So you are saying number 1?
Yes I have watched this video a few times and the way he has installed it did not work at all for me, the weather strip is too dense and with the long lip on the outside the weatherstrip will not collapse enough to let the door close enough.
Anyone else??
Thanks.

It takes a while for the new seal to squish to the correct shape and allow the door to close without slamming.
In the meantime you can avoid having to slam the door by moving the striker outward, then move it in later after the seal has form-fitted to the correct thickness.
