Free Delivery is not available for Over-Sized parcels, such as Exhausts, Radiators & Headlamps - For details on these items please see the 'Oversized Items' section below. 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. 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've also applied it on the glass of my car and let me advise you to not to do so. The wipers started juddering, whereas the rear wiper wasn't able to wipe the rear glass completely. Note that I've changed my wipers recently so that could also be the cause of the problems. As for the door's glass, it did quite well.

SONAX Brilliant Shine Detailer will gently remove any light contaminants from your paintwork & restore your vehicle to a just-waxed shine! Enhances the paintwork finish and gives the paintwork a velvety smooth surface and a brilliant deep shine I had recently tried 2 of their products( Sonax Xtreme Wheel Cleaner,Sonax Xtreme Matt Effect)and was really amazed by the results. The shampoo should get a special merit for being SOOOOO lubricious and the detail some special merit for delivering such astounding beading, but it is let down by the spray head which is perhaps more down to the viscosity of the product than the performance of the spray head which performs perfectly well with the glass cleaner. I can't tip a point off for that so it remains a top scoring product/combination. Purpose of using this product was purely to get the pop effect on white paint and i am satisfied with it.

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. 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. You get a litre ... mine also came with only German instruction, but it's pretty simple to figure out. For my application I diluted it 1:2 (Product : Water) which brought down its viscosity to a level where it can be evenly applied.

Strangely the comparison was being done with products which are priced almost double than BSD which caught my attention. 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. One capful is 30ml. Four capfuls is 120ml ... and a half, another 15ml = 135ml. That's seven washes from the bottle, so perhaps "value for money" is not that great but, you can omit the final stage (read on) and you could easily get away with three if not two capfuls only for already quite clean cars (again, read on).Second, do not apply onto hot surfaces, in direct sunlight and don't allow the product to dry. Spray on, wipe immediately, flip and buff. Any discolouration should be wiped over again with fresh product. But with BSD it's different. There is a lot less dust attracted to the paint now, the Jopasu duster doesn't requires more than three passes for the roof(required 4 passes for the Formula 1), and water beading is very good. I was able to dry my complete car with just one microfiber after coming from a drive in the rains whereas, earlier it took me more than three microfibers. First, although the instructions do say to wash and leather dry, that last part is not strictly necessary - you can sheet rinse and use this as a "wax it wet" product. This is how I used it today, with two approaches: first, using Sonax's wash and dry shampoo and second, using the same shampoo but rather than do the dry stage (as instructed), I sheet-rinsed.

To test the durability and longevity I will only do a rinseless wash for the next month or so UNLESS the vehicle gets solied during rains.It also provides very good protection. The birds poop which would earlier leave a orange coloured spot on the paint (if i cleaned it after a day), was now unable to leave any spot even after sitting on the paint for three days. Very economical product, a little really goes a long way and you can literally do an average sized panel in a couple of sprays.
