So for 24/7/365, outdoor ponderosa pine entry gate? The more penetrating and natural color as possible.

Hi:I have a question that I think I know the answer to, but I’ll ask it anyway. We put the deck stain on the day after sanding,(weather said 0 chance of rain), but 3 hrs after application, we had not a shower , but a deluge! Tried blowing the excess water off , but 4 days later, it’s still tacky. Will we have to re-sand and re-apply??Thanks
