The sealant test may have to wait till spring as want it on fresh clean polished paint which will take place after winter. It's getting more complicated by the minute though!
One thing I'm really interested in is the question of whether wax and Gtechniq C2V3 and other similar sealants can really work together. I absolutely love the velvety depth and gloss finish of a good wax, which is key to making Deep Black Pearl look it's best IMO. But I'm also interested in the merits of nano sealants and synthetic polymer sealants. There is such contradictory info out there on what order is best if you are using wax with it.
For instance many say that C2 needs bare clean paint in order to bond properly, and that wax will not last very long on top. And others say you should put wax on first and then top with the sealant. But although C2 gives great protection and has good reflective qualities, I'm not overly keen on the hard sterile, glassy finish it can give. It doesn't match the lovely finish good wax. There's a trade off I think. The finish is as important to me as the protection.
There's a lot of Gtechniq fanboys out there on other forums who will have you believe that nothing can better it, but I'm not convinced. I don't doubt the likes of C2 delivers on the durability and longevity of protections front, but I've yet to see anything of it to convince me of it's superiority in the finish and beading stakes, over a traditional sealant/wax combo. It's quite subjective, so only way to find out is to test it myself. So I will probably try:
panel with sealant only on bare paint
panel with sealant and wax on top
panel with wax on bare paint and sealant on top.
May run out of panels, haha. Will have to do a chart to remember what on what panel!
