what polish / wax is the best then ??
Sorry, didn't see this question until now. I don't want to recommend any polish or wax, because it is a never ending project to find the perfect combo. Every detailer has his/her own favourite products.
However I can say what I have been using on my current cars and my experience so far.
My Candy Red Focus used to get Swissvax Shield for a period of time, but I changed to Swissvax Concorso a couple of years ago. I also tried to switch from Shield to Swissvax Glacier on my white 108. I love working with Swissvax because it is very easy to work with and it the results are really good. My experience so far is that Shield is more than good enough for me and it was unnecessary to buy Concorso and Glacier.
Also, I'm thinking about switching to PolishAngel Master Sealant during winter (for both my cars) and keep the Swissvax during the summer. The reason is that carnauba wax is not as lasting as a synthetic coating. Considering i put the winter protection on in september and are not able to put summer protection on until april, I need something that last longer than wax.
Another ongoing project I have is to try Meguiars Liquid Wax on one half of the 108 bonnet, and the Swissvax Glacier on the other half to see which last longer. Liquid Wax is a very cheap product and is beading more than Swissvax that are sheeting (more than Liquid Wax). I prefer sheeting because i don't want the rain drops to stay on the car (beading), but a friend of mine tried the Liquid Wax and said it was really good. I obviously cannot vouch for that, but I'll give it a go. No need to buy expensive products for a cheap car if the cheap products works fine.
So how is it working for me? This is one of many pictures I took of my 4 year old Focus when it had no protection this spring (I took several images to document the paint in a detailing forum). Important information is that I never use clay or polish with cut, but use chemicals and a Swissvax polish with no cut instead.
Does this mean the products I use will work for you, and that your brand new 3008 will look just as good after 4 years if you use Swissvax?
No, not really. But hopefully you get some ideas based on my experience, and I hope that will inspire you to find products you like
