Reattach protector door strip

[sdr]

Found out yesterday whilst washing the car that my drivers side door strip has started to peel away just under the door handle.

What is the best way to stick these things back down to the door?

Just use some 3M double sided tape, its around $12 a roll last time I checked. Its considered a bit safer to use than Sikaflex, albeit not as effective...
