Recently purchased chrome and stainless steel accessories from CTD-Germany. I purchased the window surround, mirror covers, front grille and side vent covers. This question is for those of you who have installed these items. The only part I am having trouble with is the side vent covers, instruction say double faced tape is included. Upon checking the parts There was 2 tubes of label less adhesive, and no instructions on how or where to apply the adhesive. I really don't want to put any adhesive on the car unless needed. Any info or help would be greatly appreciated, I contacted CTD-Germany and I am awaiting a reply.
