i wouldnt clear coat it, tends to turn yellow and peel with age. just keep polishing, as long as you keep it up the initial polishing is the worst and a quick buff every couple of months will keep it looking nice. since i live on the coast i usually wax after polishing to help fight corrosion. i have a buddy who owns a detailing buisness, and when he gets a bike the price is dependent on the amount of chrome/ polished aluminum. my dads harley cost an arm leg and both testies. and took about 5 hours to detail
