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. In my constant endeavour to try different products this time I set my eyes on Sonax Brilliant Shine Detailer.

Systematically pour over the car ... the thin film of water will drain off and dry. Do not do this on hot panels or in sunlight. Strangely the comparison was being done with products which are priced almost double than BSD which caught my attention. Purpose of using this product was purely to get the pop effect on white paint and i am satisfied with it.

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. I had recently tried 2 of their products( Sonax Xtreme Wheel Cleaner,Sonax Xtreme Matt Effect)and was really amazed by the results. 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 find it interesting how all these auto-care product companies create these product lines that are devoid of practical information on their contents and properties. Allowing their customers to then understand how to use them as tools to achieve their particular goals. Sort of the “give a man a fish or a fishing pole” thing.

Why did you go with this, because in my opinion The Turtle wax Ice seal and shine is way superior, and with the turtle wax brand launched just a few months ago, availability and price isn't an issue.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 also do not see this as a product that requires a strict cure period. As soon as I apply it to the paint I can immediately rinse it and notice that amazing water behavior. I have not tested long-term durability at this point. The longest I've had it on the test car was two weeks under intense Florida heat and almost daily rainstorms, and the beading was still outstanding. I'm constantly cycling products for short-term testing, but I plan to also try long-term testing in the future. SONAX Brilliant Shine Detailer will gently remove any light contaminants from your paintwork & restore your vehicle to a just-waxed shine! For my application I diluted it 1:2 (Product : Water) which brought down its viscosity to a level where it can be evenly applied.

But as soon as I washed it with 3M's car shampoo, the water beading reduced to a great extent. I'm clueless about this. 3M does mention that it is a pH neutral shampoo but cannot find anything which claims that it is safe for wax/sealents. I don't know if other members face similar problems. I think from next time I'll be buying Sonax car shampoo.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. Enhances the paintwork finish and gives the paintwork a velvety smooth surface and a brilliant deep shine
