Khun Joy krab... I have a question about the spray ..

- After spraying ... How is the colour of cowhide krab ? Get darker ? I just orderd a new Montsouris ( big cowhide on the bottom )

I live in Belgium krab and here..always raining .. so I think that it is a good idea to use waterproof spray krab.. but I 'm worried about the coulor of cowhide after spraying..

Thank you very much
