I stick with recommended coolant, and change it every three years or so as per service recommendation.

I'm not sure about the for life coolants. I'd be worried that they have the correct corrosion inhibitors for a particular engine, as this is the a crucial determinant of the manufactureres' original choice.

BTW at ten years its also a good idea to reverse flush radiators and replace thermostats, hoses and temperature senders.

While considering vehicles left standing for lengthy periods, we must also remember that brake fluid sucks in water content over time leading to corrosion in the disc calliper cylinders and pistons, and worse, vapour locking in use. A partial solution is to change the fluid for new when laying up the vehicle and to put cling film under the reservoir cap to seal the system (but remember to remove it before using the vehicle). Same applies to hydraulic clutch systems.

Also for stood up vehicles, tyre flat-spotting can become an issue quite quickly
