Just came across this was surfing and learnt (What is so great about Swissvax? - BMW M3 Forum.com (E30 M3 | E36 M3 | E46 M3 | E92 M3 | F80/X))Everyone should read
(Many of the products you listed are made by the same people and private labeled and sold under different names. The colors might be different or the smells but the base formula is the same. Many wax companies claim "50 % carnauba content" when other manufacturers have told me about the most carnauba content one can mix is more in the 30% range. So carnauba is carnauba, doesn't matter much if it's white, yellow, gold, pink or purple....it all comes from a plant. Solvents must then be added to reduce the rock hard carnauba into the pliable product we know it to be. This is why it is argued paste waxes can't be layered, because the second layer replaces the first. This is due to wax laying on the paint and not bonding or cross linking.Then there is Montan wax which comes from mining.....liginite or something like that if I remember correctly.
Then we have a cheap filler of sorts, paraffin wax. I use hot, melted paraffin wax a lot to dip my hands in as it gives me great relief from aches and pains associated with a heavy day of polishing.
Let's not forget beeswax also....and we also have a line of synthetics which many waxes are now being mixed with to make a hybrid carnauba wax. So again my point is not to discourage you from using the wax or sealant of your choice but rather to say that there isn't a great deal of difference between car wax "A" and car wax "Z". You can't add "oils" to the paint nor can you "nourish" paint. Reason being is that wax is much larger, on the molecular level, than the tightly cross linked paint it rests on that it can't penetrate it. On a manufacturing side, an 8oz tub of wax costs....maybe.....a few bucks to make. I'm talking cost of ingredients, not marketing, employee and such.
So when you see a product that advertises that you know they are incorrect . A polymer can and does cross link with the paint and certain solvents, such as kerosene and water (water being natures solvent) can be temporarily soaked up or absorbed by the paint. When it rains your clear coat can soak up water. To reduce or hide swirls some old timers rub their cars down with kerosene which swells the paint causing the swirls to temporarily be hidden....it's like Botox for your car)
Kerosene really....
