yes,
to neutralize the contamination of the edge kote which is a product in aqueous phase it is possible to apply an acrylic varnish on it. ( mat or glossy )
Hi,
I have never noticed any problem with this product on vegetable tanned leather,but,but if I were you, I'd try to varnish it once the edge kote is dry, just to see.
hé hé,
the customer ( myself ) wanted exactly that, simple, zen, no frills.
Now, for another customer why not,something more elaborate, but it will be a different product.
