Hello Roger! I have a bridle leather portfolio that I take with me everywhere. It is kind of a satchel that I just hold under my arm. Where my hand holds it it seems to get tacky and slightly greasy from my hand oils and sweat and you can see the finish looks different where hand contact usually is. I applied some degreaser to those areas and rinsed with acidifier, but now it seems that there are some finish issues remaining. It isn't as shiny in those spots as it once was. Would this need some sort of protector, or rather a topcoat? Thanks! Below are some pictures where you can see dull spots relative to the shiny spots.
