I have been reading the threads regarding which is the best wax/polish. We have been told by various people (panel repair shop etc) that the best thing to use is a product called Mr Sheen. This product is a Furniture polish which is silicone based and has other solvents and polishing agents. I do not know if it is available in the USA but here in Australia it is widely used on furniture. What are you comments on using this type of product? We have a 76 450SL in excellent condition inside and out with 160000kms.
