Cuprinol do a restorer that removes the grey surface, it is actually for timber furniture which will have a planed finish but might work on your panels.

It's the grey look I'm after ideally!


Find a manufacturer and ask them not to treat the panels you want to buy.
They will weather faster and last just as long as the treated ones.

They only rot if they are too thick to dry out occasionally.
The drying out kills the rot.

Failing that find some that use real creosote as that washes out quickly
and has no effect after about a year or two.
