Cabriolet Roof Cleaning + Matrix Blue Video

This Audi A5 had its cabriolet roof cleaned, re-weatherproofed, and we also gave it a machine polish and a ceramic coating of Matrix Blue.

We began by cleaning the roof, which we do with mechanical brushes, which help loosen the dirt along with a reasonably  strong detergent to break down any lichen, moss and algae. Then we rinse it off with lots of hot water. Our pressure washers heat the water and put out a high volume of water at lower pressure, so there is no danger of damaging the roof as there is with normal pressure washers.  At this stage we also cleaned out all the guttering in the scuttle where the roof is stored when it's down, and checked all the drainage to ensure it's clear because convertible cars are prone to leaking.

We then use an aid blade to remove as much of the water as we can, this helps to make it dry quicker, more evenly while avoiding watermarks from limescale. Then the hood needs to be left to thoroughly dry, as you can't put waterproof coatings onto a wet roof for obvious reasons.

As convertible cars have no door pillars or window frames, the car is sealed by the windows pressing up against the door rubbers, which over time can become dry and misshapen. So we treat the rubbers with Krytox to make them supple, plump them up and ensure they are a good waterproof fit.

Then the hood can be treated with our two-year waterproof coating, so it will repel water which helps keep it stay clean. 

This car also got a two-state machine polish and was finished with a coat of Matrix Blue ceramic coating to help it stay looking new.
