Next month will be my FL2's 5th birthday. So after the Scotland Trip last month, 3 hours were spent machine polishing the wheels to get the marks out, which has worked well as 95% of them have gone completley, a bit more effort and the rest will be gone.
I also masked off all the trim and machine polished the whole car to remove any slight swirl marks. (Not that there were many!) I figured I may as well keep her for another year now.
Near on 4 1/2 years ownership so far, the longest I have kept a car so far!
