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.

Rust-proofing the underside has to be a good thing.

I don't think that Waxoyl does a very good job, it certainly didn't work on my old minis.

I think that there are better products available from Wurth and Bilt Hamber that offer a dry wax protection rather than the oily mess of Waxoyl. If you ask in the classic car section of the forum I am sure you will get some helpful advice and recommendations about which products are most effective.

Bilt Hamber Electrox is a great product - I don't use it on cars, but on boat trailer chassis, where we've had to cut or drill through steel that was dip galvanised and have therefore left exposed steel, which rusts very quickly in salt water environments.

I recently checked a winch mounting plate that I cut the corners off 9 years ago - not a sign of corrosion. I don't paint over it, but I think that you can - so I'd do a good brush coat of this and then cover it with satin black or stone chip.

I used Waxoyl when I had a Defender, as the previous owner had treated it with this: the chassis corroded anyway and it's very messy.
