Was wondering if anyone had trouble installing the DEGs w/o the tool provided. Seems as whenever I hammer on part of the piece in another part pops out.

 

I wouldn't even bother with the Acura door edgers. They're nothing but painted metal which kicks and chips like the door edges you're trying to protect, only you're chipping the door edge guards instead ..... DUH!!!

You're better off with pliable aftermarket stick-ons which won't chip and offer protection against dinging other car doors when you accidentally open your door into someone else's.
