How to Renew the Roof of a Smart with Veneto Auto Extreme

See how to renew the polycarbonate roof of a Smart using the specific Kit from Veneto Auto Extreme, available on the website venetoautoextreme.it. The Smart Kit is designed to regenerate the polycarbonate surfaces of this vehicle, including the roof, windows, etc. It costs £59.00, and now the YouTuber shows how to use it for the best results: remove the hazy layer to create a micro-smooth surface for applying the regenerating liquid.

Start sanding with 400 grit, removing the hazy layer with an abrasive disc on a foam pad: you can work either dry or wet, using circular motions, continuing until the surface is smooth.

Continue sanding with progressively finer grits (800/1200/2000), alternating circular motion with horizontal and vertical strokes. With 2000 grit, it is advisable to use water for a cleaner finish.

Use a compressor to remove all traces of dust, dry thoroughly, and then use the special cloth provided in the kit to give an anti-static effect. Pour all the liquid into the kit's tray, soak the applicator, start from one side and proceed towards the centre with long, continuous strokes.

Never go back over an area already covered while the product is still wet. Do not cross the strokes, but cover with parallel strips; the streaks will disappear on their own as they dry. Leave the vehicle covered for at least 4-5 hours, and avoid getting the roof wet for at least 24 hours.

The roof will return transparent and shiny as new. Pay close attention to the sanding: a rushed job will show in the final result, as will meticulous cleaning and care in the 'single pass' of the product.
