I have some acrylic varnish (mat) in a spraycan, but what I still don't understand is how this varnish solves the fact that the glue inside the jacket is affecting the leather. Mine still looks good, though I feel the stiffness, so I really want to save what I can. Maybe some kind of leather grease or vaseline would also do the trick and block the glue?
Guys, sorry to bring up my post again, but please think with me. What's the logic of sealing something, when the stuff that's damaging the leather is inside? I fear that the effects will be short term, maybe the varnish will hold together the upper layer of material for a while, I don't know, but it can't solve the problem, right?
