Japanese car-maker Nissan has unveiled a 'self-cleaning' car with 'nano-paint technology' that repels dirt before it gets a chance to take hold on the paintwork.

"The Nissan 'Note' is the first car to trial paint technology which could make car washes obsolete," a company spokesperson was quoted as saying.

The 'super-hydrophobic' and 'oleophobic' paint also repels water and oils, media reports said.

According to a company press release, "by creating a protective layer of air between the paint and environment, the technology effectively stops standing water and road spray from creating dirty marks on the car's surface".

The 'Ultra-Ever Dry' technology may cost around USD 750 (Rs 45,000).
