Is there a big difference between using Resolene on the corners as opposed to acrylic paint + CPR? I've seen both used on here with great results.
Im not sure, I haven’t tried the acrylic paint with cpr method yet. I know the resolene gets its colour from leather dye, so It works well to re dye edges as the colour penetrates well. Im not sure acrylic paint would penetrate as well, but someone who has actually used that method can hopefully comment on if the paint flakes off or fades over time. i find once the resolene has been brushed on, its pretty permanent. Hope this helps

eta: for very heavy colour loss, resolene would not work because it would require multiple layers to cover the damage and it will just turn into a rubbery mess. It really only seems good for faded colour, not total colour loss
