In one embodiment, the present invention relates to amine-functionalized polyisobutylenes. Methods for preparing the amine-functionalized polyisobutylenes are also described. Furthermore, the invention relates to microemulsion coating compositions comprising the amine-functionalized polyisobutylenes which can be applied to various surfaces, especially metallic vehicle surfaces, wherein the compositions form a protective barrier on the surface and improve the drying rate, protection and shine of the surface. The coating compositions have a long service life and withstand numerous washing cycles. Moreover, the coating compositions when applied to surfaces, hydrophobize the same and allow for easy removal of water by increasing the contact angle of water droplets and thus reducing the "footprint" thereof.
