would a car benefit by first applying sonax hybrid wax then net shield.for a better and longer lasting shine

No you do not want to apply a sealant over a wax. You can apply a wax over a sealant if you'd like but in this case it really isn't needed

Is this good on black paint? any gloss?

Polymer net shield gives a super gloss finish on my black 911 . This is a great product. For an even greater gloss , cover with a good carnauba wax like zymol

Is traditional wax completely unnecessary with this product? Does this protect against sun damage like a carnuba wax does?

Carnauba provides a superior "wet look" appearance and protection. However this product will provide protection and last longer.

How should i wash my car after applying this sealent? should i use water only or i can use car shampoo without damaging the sealent?

Good question. I've had this product on three cars for a couple of months now, and the two garaged look like it was just applied yesterday. The outside car I'm thinking I will just hose with water only. I believe, however the product will stand up to appropriately mild auto soaps, but I would then apply The Sonar Brilliant Shine Detailer if necessary. Also, you can contact the US Sonax distributor. I emailed them a few questions when I transitioned from PS21 to this product.
