Keen, welcome to the Forum!
As you are starting the 230SL project, I am sure you will find a lot of priceless information here.
A good practice is to start from New Members Introductions within General Discussions section.
For the Members to be able to help you it is important that everyone is, indeed, following the order that is suggested in the header of the Forum: check the Tech Manual, use the Search function and then post a question if you still have not found what you were looking for.
As stated in the previous reply, you will find the answer to your question on the Forum - I think almost all has been said on this topic, including paint codes, details such as wheel wells painting etc.
I am sure you will come back with a lot of questions as you go through the project and fellow Members will be happy to help. You may also find it usefull to join Full Members as more is available for them.
For future clarity and reference it may also be useful to post threads in certain section, e.g. yours would probably best fit Body, interior, paint, chrome, and cosmetic items.
Good luck with the project!
