Alternative to Cuprinol Ducksback Shed & Fence Treatment

[quintain]

Hello

Can anyone recommend a reasonably priced alternative to Cuprinol Ducksback Shed & Fence Treatment 5L Forest Oak

I generally pay £13.00 including delivery for 5l at https://www.toolstation.com/ but they cannot supply at this time.

Amazon have an advert for 5L with a price of £40+ and similar on Ebay.

I need about 100l of the above or a suitable replacement with long life (3-4-5 yrs or so) expectancy, that can be delivered to me.

I would welcome any advice that you can offer.

Best Regards
Richard (quintain)

I find Ducksback has a waxy finish some other products do not stick well to in unless very weathered.
