    Sunlight has more effect on the car condition over rain.

    Yup, waxing helps pretty much then add some rubber conditioner to the rubber mouldings/parts. Also, consider the tint and sunvisors/sunshades to minimize the intrusion of the sunlight into the car interior and wiper ups (or at least raise your wipers) to keep it from cooking on the windsheild.

    In my experience, sunlight mas matindi effect kesa sa rain. UV + intense heat.

    TIA.

    modern automotive coatings are designed to resists the effects of rain and the uv light of the sun. but between the two, it's the sun that does more damage. the damage that rain causes will only happen or will be exacerbated by the effects of exposure to the sun. for example, rusting of panels will only happen if water manages to seep into cracks of the paint and paint will only crack if it is repeatedly exposed to the sun for a prolonged period. rain per se is pure water, it's nature's version of distilled water unless, it dissolves sulfur dioxide and other dust and particulates coming from auto emissions w/c causes the so called acid rain. only then will rain become a harmful agent due to it's acidity and the residue that is left on the car's coating when it is again exposed to the sun. Again,the dust that deposits on the car's coating will only become harmful if it's exposed to the sun since it's like baking dust particles on the surface of your coatings. on the other hand, UV light from the sun can destroy the polymer binder that makes up your car coating thru so called chain scission mechanisms - simply put, it can cut up the molecules that comprise your car's coatings. although most automotive coatings are formulated to contain so called anti-uv additives or UV-stabilizers, then will only work for a while. so as your car ages, so does your car's coating, unless your car is only used at night and is always stored under the shade, so automotive refinishing or re-coating will sooner or later become necessary.

    di ko po galing sa google yan... stock knowledge, since formulating coatings for various applications is one of my work areas. hth ;D

Greater effect: Sunlight or Rain?
