But the protection it provides is phenomenal. Before this I was using the Formula 1 Carnauba Wax and it did provide a warm finish to the paint, but wasn't long lasting. Also I found, that in comparison to the BSD it attracted a lot more dirt. And within two-three weeks it would require reapplying. Several days after applying Sonax Brilliant Shine Detailer, this car sat out in a pretty good rain storm. I went out to examine the beading action, and was pleasantly surprised. Even though the vehicle already had a good layer of protection, which beaded nicely on its own, I noticed even better beading and sheeting when it was topped with Brilliant Shine Detail Spray. I have no idea if PNS is even helpful in this usage scenario. If the BSD provides the same protection (albeit, for a shorter period of time), and you wash your car periodically anyway, the after-wash BSD treatment should provide the same protective benefits to the car’s paint. SONAX Brilliant Shine Detailer will gently remove any light contaminants from your paintwork & restore your vehicle to a just-waxed shine! However this can be achieved by mixing it with other products like v7 but its not available in India.

I had recently tried 2 of their products( Sonax Xtreme Wheel Cleaner,Sonax Xtreme Matt Effect)and was really amazed by the results.Strangely the comparison was being done with products which are priced almost double than BSD which caught my attention. The shine left behind by BSD is great. Maybe not quite as good as that left behind by my AngelWax QED, but for the water beading lovers, it's practically untouchable! In my constant endeavour to try different products this time I set my eyes on Sonax Brilliant Shine Detailer. The trigger bottle isn't great. Once you get to two thirds down the bottle, it is difficult to get the last remains out and it just spits a few droplets at you. However, this is the only thing that does let it down. I can't comment on durability, as I've n ot had long enough teat this, but I'm confident that it's everything it claims to be.

Purpose of using this product was purely to get the pop effect on white paint and i am satisfied with it.

So, my running assumption (without any supporting info) is that a single coat of cured PNS—which cannot be layered because the solvent of subsequent coats will simply melt off any previous coats—is the intended usage of the product. Then, supplementing the PNS coating with BSD after washes, and between reapplications of PNS every six months. For my application I diluted it 1:2 (Product : Water) which brought down its viscosity to a level where it can be evenly applied.
