Reusing cladding question

[Nemesis379]

Hello,

I'm going to be reusing tongue and groove cladding, first it's going to be sanded and then painted.

My question is should I use something like Dulux Weathershield - Exterior Preservative Primer and then Cuprinol 5 Year Ducksback (colour I've chosen is from this brand), To make sure that the wood lasts a long time.

Thanks!

You reckon it would be OK to use Barrettine Premier Universal Preservative with Both Cuprinol 5 Yr DucksBack (for the entire shed) and Ronseal 10 Year Exterior Wood Paint (for the wooden trim)?
