So I bought 2 sets in case i messed up the first one.

As far as i can tell, there doesnt appear to be adhesive inside the trim gard, it just looks like it clips on....should i apply my own adhesive?

The directions no the back of the package says to wipe down the intended area, and to install these in temperatures above 65 degrees Fahrenheit. Should I just assume that there is some sort of adhesive inside the clips and just trim them and stick them on (when the temperature is alright outside?) or should i go ahead and buy some sort of adhesive (which would be my follow up question) and then put on the door edge guard?
