Really wish I had not viewed this thread! Thought my SL was "reasonably" clean under the bonnet . Now I realise it is actually rather shabby and I need to spend a lot of time cleaning and painting. I will have to send you an invoice! What paint did you use one the rocker covers,and have you had any issues with it flaking/cracking? I was thinking of getting mine machine polished , but not sure if they will buff up that well.
cheers
