1 Litre of Nikwax TX10 spray on fluid, for £14.34, which i thought was excellent value.
My lite weight waterproof, is losing a bit of its water repellency, and its been ages since ive bought any of the Nikwax products.
I thought £12-13 for 500ml, was a bit much, but that appears to be the going rate.
Its very easy to go through the 300-500ml bottles extremely quickly, so a Litre for just over £14 is a Result in my opinion.
