Help installing a Riger front spoiler lip and window cover
 

Hello to all the fine gentlemen on mercedesshop forums.
I recently got a front Riger lip and a back window cover for my baby, which is a 1991 190E 2.6
Unfortunately the instructions and what appears to be "compounds (i.e P1 Elastisch Halfstark Scheifbar , Primer 324, Reiniger und entfettet lackierte Oberflachen ) are in german. I realize now i should had taken german in high school instead of spanish :D but anyways i'm stumped.
As far as in figured out , the front lip comes on top of the lower fascia ( DUH, that's a no brainer ) and the back window cover comes on the top of the back window ( again DUH ). But which "compounds" will i use to glue the front lip to the body??
Also the back window cover comes with some sorts of brackets ( if need be i'll post pics of them ) , which i believe i'll have to insert them into the back window gasket , but how will the back window cover will be attached to those brackets???
I really appreciate any input and if someone knows german i can scan the instructions and e-mail them.
My baby is a 1991 2.6:
