Hi mate,
I use the following on my White Leon.
Poorboys White Diamond (especially formulated for light coloured cars) to fill the swirl marks and to add a nice shine and FK1000p as a sealant.
Process:
Wash car (Zymol), don’t dry it afterwards.
Clay with Bilt Hamber Auto Clay bar. As car is still wet it acts as a lubricant for the clay bar.
Wash car again (Zymol), then dry off.
2 coats of Poorboys White Diamond.
1 or 2 coats of FK1000P to seal the Poorboys. You can also use this on your alloys as a protection against brake dust, etc.
Takes a while, but I do this only about 3 times a year and get great results.
You will see the amazing beading results from the FK1000P which normally lasts 3 or 4 months.
I was advised over on detailing world not to use a wax on white cars, but to use a sealant, like FK.
Hope this helps!
