The use of an adhesion promoter is highly recommended and advisable to maximize the effectiveness of the adhesion.

One individual use packet is included which is acceptable for small areas.  Alternatively you can purchase your adhesion promoter from Amazon, 3M or auto/marine accessory web stores.
We carry individual packets of 3M Adhesion Promoter 06396 and 3M Adhesion Promoter 4298 (both are used in the same manner and have similar results), but customers have had success with other non-3M brand adhesion promoter products. We do not recommend the sprays.
