A:AnswerHi there, this is Kaleb with Bracketron. Thank you for your question! This Lux mount uses patented Temporbond suction technology which includes an adhesive on the rubber suction cup to stick to your dashboards surface, therefore you shouldn't need any additional adhesive. Before applying, make sure you clean off the dash of any dust or residue, and the mount will suction! For any further assistance needed, please reach out to [email protected] and we'd be happy to help. Thanks, Bracketron Support
