Want to polish the car soon as I've never done it since owning it. It's silver metallic so any recommendations on a good polish for this colour? Was thinking of AutoGlym seeing as it's a good all rounder and easy to use by hand? Or is there something at a similar price that will be better? I don't really need anything with an aggressive cut though. Just wanting to enhance the shine and give it abit of protection at the same time.

Secondly whats the best method to apply it? I've got some sponge applicators, do I just change it if it becomes caked up and then wash it out? I tried washing one under the tap, needless to say I quickly gave up is it easier just to bin it and get new ones?

Thanks in advance
