Underbody protection / your opinions …

Hello, Will you improve the underfloor protection complet at my Cr-v (6500km) on the weekend. Since the car hasn’t seen a winter yet,I think it makes sense to do it now. Why do I do that? Would you like to drive the car for a very long time,I think that it can’t hurt to protect and seal it right from the start. I’m interested in your perspective on this topic, did you also take precautions? Do you think it’s nonsense? . . .
