applying adhesive material at the seams or joints, arranging the adhesive material to rest directly, at least in part, on the sealing material, and causing the sealing material to flow into the seams or joints under the weight of the adhesive material as a result of the adhesive material having a higher viscosity than the sealing material in a liquid form of both the sealing material and the adhesive material. ### Claim 2 (depends on 1) The method of claim 1, wherein the adhesive material is a material of higher viscosity than the sealing material, which is an elastic, solvent-free, liquid-curing material. ### Claim 3 (depends on 1) The method of claim 1, further comprising applying the adhesive material in the form of a bead. ### Claim 4 (depends on 1) The method of claim 1, further comprising applying the adhesive material to the sealing material in substantially crossover form. ### Claim 5 (depends on 1) The method of claim 1, further comprising applying the adhesive material to the sealing material in substantially parallel form. ### Claim 6 (depends on 1) The method of claim 1, wherein the seams and joints are defined on body components of motor vehicles. ### Claim 7 A method for adhesive bonding and sealing comprising: applying elastic sealing material at or in seams or joints of at least one first component; applying adhesive material in the form of an adhesive bead to the sealing material immediately following the step of applying the sealing material such that the adhesive bead substantially covers the sealing material at locations which are to be sealed; causing the sealing material to flow into the seams or joints under the weight of the adhesive material as a result of the adhesive material having a higher viscosity than the sealing material in a liquid form of both the sealing material and the adhesive material; pressing at least one second component, which is to be adhesively bonded to the adhesive material, onto the first component with the sealing and adhesive materials applied; and curing the sealing material and the adhesive material. ### Claim 8 (depends on 7) The method of claim 7, wherein the seams and joints are defined on body components of motor vehicles. ### Claim 9 A method for adhesive bonding and sealing comprising: applying elastic sealing material at or in seams or joints of at least one first component; immediately following the application of the sealing material, applying adhesive material in the form of an adhesive bead to at least one second component, which is to be adhesively bonded to the at least first component, in a manner corresponding to the applied sealing material at locations which are to be sealed, and such that the adhesive material covers over the sealing material, the result of said application being that, when the at least second component is joined together with the at least first component, the adhesive material substantially covers the sealing material at locations which are to be sealed; causing the sealing material to flow into the seams or joints under the weight of the adhesive material as a result of the adhesive material having a higher viscosity than the sealing material in a liquid form of both the sealing material and the adhesive material; pressing the at least second component, with the adhesive material applied thereto, onto the at least first component with the sealing material applied; and curing the sealing material and the adhesive material. ### Claim 10 (depends on 9) The method of claim 9, wherein the seams and joints are defined on body components of motor vehicles. ### Claim 11 (depends on 9) The method of claim 9, wherein the adhesive material is applied directly over and on top of the first component, the second component and the sealing material.
