No problem over the advice pal, although its hard working on the paintwork, BMW paint can mark up easily if you aren't careful. Tripple should indeed clean up any marring nicely. Worked on an EB over the weekend ;-)
I don't find AF Tripple mutes flake pop, but it's not the best product for longevity under a sealant (like Werkstat) - I prefer to use AF Tough Prep for sealants, as it leaves a great finish combined with a perfect base for the sealant.
EB looks fantastic with Super Natural Hybrid over Tripple though. A real deep wet finish with around 4-5 months protection
