I bought the kit long time ago, and installed it long time ago using equally spaced rivets. Actually looked better then i thought it would. Recently got in to a small accident in the front, not my fault so the other person is paying. My front bumper is going to get changed and i want to get rid of the rivets. An autobody shop is doing that but i want to advise them on how to do it right without rivets and still keep the lip on my bumper at high speeds. Now that i think about it the kit came with some tubes of something i am not sure if its epoxy or just filler, its in German. I also have instructions which are in German also.

Any advise is appreciated.
