Undersealing?

[krisasthecolour]

Hi guys, recently acquired a lovely low mileage late 2017 Nismo and I intend on keeping it for a long, long time. I was wondering if anyone had undersealed their 350 or 370 to protect against the salt on the winter roads? I know it's a must-do on JDM imports, but mine is a UK release and I've read differing opinions on whether undersealing is worth doing or a waste of money? 

 

Any and all opinions appreciated 👍

I don't use underseal as it can dry and crack.  I jet wash and then use Bilt Hamber Dynax.
