metal surface to be plated. ### Claim 2 (depends on 1) Apparatus according to claim 1, wherein said means includes a plurality of hand manipulated applicators, each of the applicators being adapted to apply a different chemical solution on a metal surface to be plated, and wherein each of the applicators is connected to an electrical conduit, each of the conduits in turn being connectable to the D.C. power source. ### Claim 3 (depends on 2) Apparatus according to claim 2, wherein the electrical conduit for each of the applicators is attached to means on the applicators for relieving strains on the conduit during plating of a metal surface. ### Claim 4 (depends on 2) Apparatus according to claim 2, wherein each of the applicators is adapted to releasably receive a metallic anode. ### Claim 5 (depends on 4) Apparatus according to claim 4, wherein each of the metallic anodes is provided with a chemical solution absorbent cover for applying a chemical solution on a metal surface to be plated, said cover serving also to inhibit contact between the anode and said metal surface. ### Claim 6 (depends on 5) Apparatus according to claim 5, wherein the absorbent cover is made of cotton, said cover being closed at one end to prevent contact of its associated anode with a metal surface to be plated. ### Claim 7 (depends on 2) Apparatus according to claim 2, wherein means is provided on the support member for maintaining the applicators in a suspended position above the chemical solution receptacles, said means further acting to maintain the electrical conduits in spaced apart relation to prevent entanglement and contact of the conduits with the chemical solutions in said receptacles. ### Claim 8 (depends on 7) Apparatus according to claim 7, wherein said means comprises a rack having an inner member on which a portion at least of each of the electrical conduits is supported, and an outer member for supporting the applicators. ### Claim 9 (depends on 8) Apparatus as claimed in claim 8, wherein the applicators are provided with clips for releasably suspending the applicators on the outer member of the rack. ### Claim 10 (depends on 9) Apparatus according to claim 9, wherein a metallic metal surface engaging clip is secured to an end of the electrical conduit. ### Claim 11 (depends on 9) Apparatus according to claim 9, wherein the clips are fabricated of a non-electrically conductive material. ### Claim 12 (depends on 7) Apparatus according to claim 7, wherein the electrical conduits comprise retractable cables. ### Claim 13 (depends on 2) Apparatus according to claim 2, wherein the D.C. power source is provided with a plurality of spaced, voltage output receptacles, each of said receptacles being adapted to receive a connector provided on each of the electrical conduits. ### Claim 14 (depends on 13) Apparatus according to claim 13, wherein each of the receptacles of the D.C. power source has its own voltage output, the voltage being automatically maintained at a predetermined level by the D.C. power source. ### Claim 15 (depends on 13) Apparatus according to claim 13, wherein the voltage output receptacles comprise banana jacks, and the connector on each of the electrical conduits is a banana plug for engagement in the banana jacks. ### Claim 16 (depends on 1) Apparatus according to claim 1, wherein the wheels for the support member are adapted to freely swivel in relation to the support member thereby enhancing the positioning and maneuverability of the apparatus. ### Claim 17 (depends on 1) Apparatus according to claim 1, wherein means is provided on the support member for storing chemical solutions and equipment employed in the plating operation. ### Claim 18 (depends on 17) Apparatus according to claim 17, wherein said means comprises a compartment for receiving a removable tray for storing said chemical solutions and equipment. ### Claim 19 (depends on 1) Apparatus according to claim 1, wherein the support member comprises a lightweight frame having an upper portion for supporting the seat, and a lower portion for supporting the chemical solution receptacles and the D.C. power source. ### Claim 20 (depends on 1) Apparatus according to claim 1, wherein said means includes a hand manipulated cathode member adapted to be maintained in contact with a metal surface to be plated during plating. ### Claim 21 (depends on 20) Apparatus according to claim 20, wherein the cathode member is provided with an electrical conduit which is connectable to the D.C. power source. ### Claim 22 (depends on 1) Apparatus according to claim 1, wherein the D.C. power source is provided with a lead connectable to an A.C. power source. ### Claim 23 Apparatus for electroplating gold on selected metal surfaces of metal vehicles, comprising a frame; wheels provided on the frame to enable it to be easily moved along the exterior of a motor vehicle; a seat supported on the frame to enable a user of the apparatus to assume a sitting position on the frame during the plating operation; a D.C. power source carried on the frame; a tray provided on the frame for receiving chemical solution receptacles; a plurality of hand manipulated applicators supported on the frame, each of the applicators having an electrical conduit connectable to the D.C. power source and a anode for conveying chemical plating solutions to a metal surface to be gold plated, and a cathode provided with an electrical conduit for connection to the D.C. power source and including a metal surface contacting member for engaging a metal surface to be gold plated thereby to complete an electrical circuit from the D.C. power source to said metal surface. ### Claim 24 (depends on 23) Apparatus according to claim 23, wherein a storage compartment is provided for the frame for holding chemical solutions and other equipment used in the gold plating operation. ### Claim 25 (depends on 23) Apparatus
