Dunc use the car like it was built for

i use my imperial blue escos every day and it has had the underside prepped to concours standard its only running 380bhp but no matter what the weather i use it as thats what i bought it for
since i got it in october last year the underneath hasnt deteriated i just give it a quick wash of with the jet wash to make sure there is no salt underneath
use it and enjoy it as if you sold it you will only regret it at a later date
