Best wax for my bright red 2013 Jetta TDI. I usually use collinite as a sealant, but want to put a nice coat of wax first

 

Welcome to the forum.

I don't think the colour makes any difference. It also depends where you live as to the products availabe.

I've always used AutoGlym Super Resin Polish for many years. One application will actually last 12 months and you can still see the water droplets when it rains.

Zymol pure carnauba wax or Klasse paint sealant would be a good pick your any dark colored paint.
