3. A car is not meant for rain harvesting:
Constant downpour will mean that the rainwater is going to accumulate in all the nooks and corners of you car – especially the areas like the bumper slots, indentations below the wipers/windscreen, outside rear view mirrors, door/boot handles, door rubber linings etc. Make sure you drain of all this water every time you return home as this stagnant water can cause rusting of the surrounding metal parts, while the rubber linings will lose their elasticity. To prevent the rusting further, spray an anti-rust solution every week on metal parts like the bolts, nuts, spark-plug mounts, welding lines, etc. Also make sure that the headlight and taillight assemblies don’t have holes or leaks, as water can accumulate in them and lead to short circuiting of the bulbs and related electrical components.
