Riding in Rain on a Quest

When riding in rain on a Cruz Bike Quest, should you lubricate the TFT (telescoping front tube) and seat post.(Will water get inside)
It so what should you lubricate them with?

I would lubricate

I would lubricate metal-on-metal interfaces with a standard goopy bike grease, regardless of whether I planned on riding in the rain. Grease prevents binding and creaking.
