what would happen if you applied autobahn onto your paintwork, would it lasts longer than regular wax?
It will smear and haze up like nobody's business. The amount of PTFE teflon in autobahn will try and separate from the paintwork causing the wax to look like someone rubbed melted butter onto your paint. Shield would obviously be your next best option if you're looking to try out the whole teflon thing. Shield has a considerably less amount of PTFE than autobahn.
Shield and Autobahn are the same products in Europe. I tried both and couldnt feel a difference. Autobahn is a bit cheaper than shield
