thanks for the tip but i still need to know what are the possible adverse effect (if any) on the car paint if contaminants are not properly (or entirely) removed before applying the wax. will it kill off the paint or it will just make the car less shiny.
A few possibilities:
1. For the paint itself - contaminant *could* possibly accelerate oxidation or failure of the clear coat. But this would take several years of neglect in order for it to happen.
2. For the wax/sealant - waxes/sealants adhere best on clean surface. So, if there's any contaminant, adhesion would be weaker and this would result in shorter durability or cloudy patches after application.
If you're really worried about it, then there's only one thing you should concentrate on - WASH REGULARLY. Most shampoo would leave a tiny little amount of wax/sealant. Though not enough to give proper protection, at least it's something and the surface would stay relatively clean hence minimizing contaminants to cause maximum damage.
Furthermore, most of the normal consumer range waxes/sealants also contain some cleaners in them. Taking that into consideration, the process of applying waxes/sealants of any kind would also remove *some* contaminant due to the cleaner in them and also the aggressiveness of the applicator (you'd normally see the applicator turns dirty during/after use).
Shucks...now it's getting more and more complicated. Well....if you regularly clean your car and occasionally wax it...don't worry la...most probably the car would have left you before the paint is damaged.....
