Please use the Carnuba wax!
We have a historic car collector here in Australia who has developed their own car care range. The reason was that they purchased eveything on the market, including some very expensive European brands and all the American brands and except for some of these expensive brands, the others didn't test too good and contained harmful silicones.
They started out only producing enough to look after their historic car collection - a good $18 million +
The story goes that they have a '65 Rustang which they restored some years ago. Their panel shop told them to use this great product on their stang. That product was Meguires. After years of using this product, they noticed a white ghosting effect in the paint on the bonnet. What had happened was the polish had made its way through the paint layer and was sitting between the base coat and the metal panel. The polish was reacting with this panel and causing this effect. They had it tested by an independant paint expert and he confirmed this effect and said the car would need to be resprayed.
The result is their new care car range -

Their products do not contain any silicones, which is good as it doesn't leave that annoying white film after polishing. I have used their entire system and found it to really produce a deep polish and really clean the old paint on our Vette. They also recommend microfibre cloths over lambs wool, and also not using ANY car covers!
I have seen their car collection with our Corvette Club and may I say it is the sweetest collection I have seen for a while, well apart from the Corvettes parked in the car park at their estate! Especially that $2 Million GT40.
I know you will not get this product as it is only sold through them or at Autobarn here in Australia. You can order it from their website though.
I totally recommend this product.
Cheers
