First serie RS Touring coating Shipping code 4

Dear Porsche friends,
At the moment I am restoring a very early RS 1972 to originality but I am missing information and pictures about how and were the coating is used for the Touring version with shipping code 4 ( waxed).

I owned a RS ( fitst 200) with shipping code 5 ( unwaxed) and there was none coating applied anywhere so the knowledge that I have for this car I can not use for the rolling restoration.

So , Who can help me ??

Looking for info and pictures of unrestored RS Touring cars from the first serie with shipping code 4!

Also very interesting is where the paint colour hits the coating in these cars . I do not want over restore this very unique car and my gain is to bring it back to originality as good as.

Thanks in advance for your replies.

John
