besides the rivets that are the most important step , i also used adhesive promoter by 3m that was applied to the area that the 2-sided tape was applied ,then i taped the front lip to the cover overnight to keep the weight from pulling on the lip while it was setting up. this step is not in the directions but it makes the 2-sided tape adhear better!!! and i know the dealer would not do anything like this to make it last longer, remember that dealer mechanics get paid book time the faster they get the job done the more they make. not knocking them al all but i know i would do a better job because i own the car and spent the extra time!!! i would not let the dealer install i did it myself and made sure it is done right.. just a fyi once the gfx are painted its voids the warranty on the gfx !! so make sure the install is done right the first time. if you search the forums someone already posted the directions from gm that come with the kit, kind of confusing but as you are doing fhem its all makes sense!! much more straight forward than most of the years of christmas presents that i had to but together that said some assembly required lol i know its not the same but not that hard to do yourself and make sure its done right..
