which is correct way install- trunk weather strip ?

Here's how to do it within 15 to 20 minutes Step 1 clean the entire area free of any debris clean it down with alcohol or some kind of an adhesive leaner that will completely remove oil grease or rust from the whole area.
Step 2 starting at center of the lock is where they originally applied the center... lay out the entire weatherstrip around so you know how much you have and how much to play with cut off excessive leaving at least two or three inches extra to be safe.
step 3 starting at the center channel of the lock center of the trunk slowly out a thin line of 3M adhesive about a foot and a half to two foot at a time...let it get tacky about five minutes and then apply in the direction shown in pictures continuously move on to the next section is slowly unevenly on the corners I used potato chip clamps to hold it in place so did not move
