Protecting New Decking

[planemad]

I have laid my new decking today which is already pressure treated.
What is the best product to use to protect my decking from the elements.

There are so many different products.

I would like to keep the natural colour so a clear coat would be desirable

Many Thanks

Decking oil, don't use any coloured coatings they all wash off in the rain leaving the decking looking terrible.
