So a follow up to my prior post and my mention of using a dedicated sealant. Well, its one of the top sealants in international market and called Blackfire Wet Diamond. What you see next to is is also a quality hand applicator known as Chemical guys UFO applicator (used to come along with their 200$ product and now sold separately).
1. Blackfire Wet Diamond All paint protection
Wet Diamond, All finish Paint Protection is a paint-friendly, oil-in-water, emulsion safe for all finishes with or without a clear coat. This emulsion contains a small amount of a very refined mineral spirit in a water base. Multiple coats can be layered to deepen the gloss without drying or weakening the paint.
2. Chemical Guys UFO applicator
The Premium UFO Wax and Dressing Applicator Pads are 50 percent larger than the traditional applicator pads. These laser-cut durafoam applicator pads are ideal for many uses from your favorite cream or paste wax to leather conditioners and dressings. The laser-cut edges form a unique UFO-like shape making them extremely easy to fit into tight areas. This unique durafoam composite of the pad assures that just the right amount of product is absorbed to reduce waste while the micro-fine pores work perfectly with the soft and dense pad construction to deliver superior surface application.
Application procedure:
The car was first washed and dried. It already had base prep done to it last week using prime acrylic.
This sealant (aka BFWD) meant to be more oriented towards mid/dark tones, but it worked great for my silver too. Good flake pops in the sun as well, not as flaky as my experience with werkstat was but when silver area is exposed to direct sun you see the specks of flakes. Its Slickness is next to nothing, things just fall off from it and you feel like swiping your hand on it again and again. It gives such a wet look that You actually feel there is oil on the surface yet you touch it and its all silky smooth. Applying it was a breeze, it was a blue text in color, requires you to keep shaking it continously. Because its oily, it spreads very well thinly.
The pictures are taken by a colleague from a camera. It was a cloudy day yesterday which is why you dont see any sun exposure.

and the pick of the lot and my favorite. The car actually looks like it in terms of reflections with decent depth:
