I use showroom shine in n mine and it works wonders especially on filler cap and anythig either painted or aluminium I also find it so easy to use and requires little or no effort to apply and shine I can not recommend this enough.
Please be aware that this polish is designed to be used with or without washing the car first but I would always recommend to wash the car first as polishing dirt into the paint is never a good idea even if the bottle says that you can.
