My A4 Cabriolet is up for sale (see classifieds) so spent the weekend giving it a deep spring clean ready for people to view. It took about 18 hours all in. It was washed, clayed, polished, waxed and sealed. The roof was cleaned and water proofed. Glass polished and interior given a good clean. I was quite happy with the results, so here are some random pictures of the finish.
