Vacuum hose and drill screw bits for tight spots. Clay bar and Mcguire detail spray makes silky smooth paint. Project cart or Tv tray to keep tools in one spot. A stool instead of the ground jack or not. Carpet runner to put parts you don't want to get messed up. A pipe over a ratchet makes a great breaker bar. Rubber gloves then mechanic gloves to keep hands clean and from getting burned. The best tool is to walk away and then come back if you get in a pickle. If you have to use a wrench and need more leverage place a larger one on the shaft side ways not on the boxed or open end you will mess up your wrench. Liquid before tight bolt grunts. Rounded a bolt use a box wrench and old screw driver. Ok that should do it well backing soda and water will clean corrosion just not on computer components. Vaseline lightly on rubber hoses to help slide them on works for floorboard tabs also.
