Help detailing a Black S3

Yes Wet Diamond is a sealant mate.

Your car may not even need claying, its more than likely that it will but we have done a few new cars that have been silky smooth so no claying was needed.

If you do then a mild clay will be all thats needed, just make sure you use plenty of lube to help keep any marring to a minimum.

Autoglym Super Resin Polish would be a good polish to use afterwards as its easy to use, will remove any light marring the clay induces and it will leave a nice basecoat for the Wet Diamond to be applied to.

Along with careful washing with the 2 bucket wash process and a decent lambswool wash mitt & Waffle weave drying towel - that should be pretty much all you need to keep it looking great

(providing the Audi dealership doesnt swirl the $hit out of your paint!)

I love the last line in that post Clark!

remember and get some pics up when you're done
