High-end microfibers are essentially those of the highest quality coming from Korea. Car Pro sell a lot of those. Think Microfiber Madness as the perfect example. Hydro2 does give you that slick glossy feel. It as well will also protect for up to 6 months.
Washing your vehicle again can be a very lengthy conversation. I usually spend 2+ hours just going over the basics....but I turn something most consider "simple" into an art...that they will say is crazy.
2 bucket method- grit gaurds
filtered water/deionized water
best mitt in the world (MM Incredimitt)
wash top down, in sections, while in a circulating fashion
use another mitt for the bottoms of the vehicle
wash wheels and tires FIRST using a dedicated microfiber or assorted brushes (careful with the brushes)
use light....light pressure when wiping....
use reset or ultimate paint guard or another very high end wash shampoo....i advise to include some Optimum rinseless especially if washing outside.
blow dry...
also, do touchless washes more....and you will find yourself hardly ever having to even touch your paintwork. Saves the stress...but also, not getting bent out of shape for every small defect saves stress too...i just don't have that ability
