No worries mate.
i had the same problem most polishes work well to fill darker cars but the white diamond is a glaze made for lighter cars and its AWESOME stuff!
You still need a wax after though but when im using the white diamond, I like to use three stages after clean, clay and lime prime.
1.White diamond glaze-Let the glaze do the work as it will go far mate
2.Poor boys EX-P sealant - this is not a common practise but I find it gives that wet,glossy look on top of the glaze and provides a good level of SRP on its own, leave it for 30 mins OUT OF THE SUN and then buff off and admire !!!
3. Wax-loads on the market but look for a high carnuba content and give it one coat , buff off as normal, then if im really looking for protection and shine, I leave the car overnight COVERED up so no dust can get on the paint work, then use some quick detail to make sure the panels are 100% clean and wax again.
Take a look in the how to guides my detail guide is in there skip to the end and you will see the finish without white diamond, with the diamond its a LOAD more glossy and gives the paint a deep finish.
You know where the woot button is buddy LOL
AND I WANT PHOTOS ASAP !!!
