If anyone knows anything that other people could use, then add them onto this tread.
1 - Is your black trim looking a little pale and grey? Beat it with black shoe polish. Just like you polish your shoes. One brush to brush polish on, and the other brush to buff it up. Makes all your black trim nice and dark again and look brand new! Don't use liquid shoe polish. Only the waxy stuff you get in those small tins.
2 - Want to remove your badges? The most easiest way to remove badges without risking damage to your paintwork is to take your badges off with Dental Floss! Badges come off really easily and in minutes. Once all badges are removed, use Auto Glym Intensive Tar Remover to get rid of all the gummy black stuff. This stuff is magic and works really well. Then use normal car polish to buff the area up. This is a really easy and quick way of de-badgeing your car.
