To wax, or not to wax?

[andy.s.964]

I've been conserving/restoring a 1990 964 Targa since September 2016 and am finally getting towards the end of getting the car back into usable condition. It's a 91,000 mile car and intended for regular good weather use. I've got no problem with it looking it's age and intend to keep it indefinitely. While the body/chassis seems to be completely good with no rust issues, I have no problem with a patina consistent with the cars age and usage.
Here's the question... Should I get it comprehensively Waxoyled and what, if any, would the implications be for the cars long term value?
Any input would be much appreciated.
