Actually, 3M makes a variety of industrial strength tapes. I'm
not talking about the mild kind you buy at Ace Hardware. 3M makes really scary stuff that if used improperly, can cause some
disastrous results.

To put on body trim/skirts/etc., its recommended to use 3M VHB (very
high bond) Double Coated Acrylic Foam tape (#4930). The thickness of the 3M VHB #4930 tape is .025" or .64mm. In other words, relatively thin for double sided tape. It has a normal tensile strength of 160psi, a static shear strength of [email protected]'F. Dynamic shear is 100psi @ room temp. Temp tolerance up to 300'F short term/ 200degF long term. Solvent resistant, moisture resistant. Dwell time (the time it takes for 100% ultimate bond strength to occur) is 72 hours. UV resistant too!

This tape simply has it all. Disclaimer, if you put it on out of
position and rub it down with pressure, good luck removing it. The work part (trim piece) will be destroyed in the removal process, or mangled beyond repair.

This tape is typically used to replace spot welds and rivets.

For any one with this still as an issue you can use 3M Super Strength
double sided stick tape and not the #4930 one. The package
says weather resistant from -20 to 200 degrees F. Make sure it is Scotch 3M Super Strength mounting tape cat. NO. 316 from home depot with a red case. It says intended for permanent use on glass metal and sealed wood.

The key is to get some bird and tar remover or some sort of strong cleaner and remove the crap from the molding itself as well as on the door. Do it a couple of times to make sure that all of the dirt is gone. Next completely adhere to the molding a strip that is as long as the area which is not sticking. In other words cut it as long as the section falling off. Lastly press firmly in all areas and hold it for at least 1 minute in each of the key areas.
