Usually when my black AW bags get worn the area looks a little faded. Is that what you are experiencing?
I have sent several bags to LMB for services but have never used their products...so I can't comment about the 'For Handles Only'. I have used Apple Conditioner and Blackrock Leather 'N' Rich conditioner on my black Roccos and have never had a problem. I also condition the handles. I have always felt that dry handles are more prone to absorbing sweat, lotions, etc.
Apple Conditioner: I normally squeeze a small amount on a clean rag and work it into the leather. It is IMPORTANT to buff the bag very well afterwards...especially pebbled leather. The product works itself into the pebbles and will turn white if too much is left behind. I lost a RM bag to this...lesson learned. Some have mentioned that this product feels greasy but I never noticed it.
Blackrock Leather 'N' Rich conditioner: I put a very small amount on my fingers and work it into the leather. Don't apply too heavy...you can always do it again if it needs it. I normally condition one side of the bag and then buff it really well with a clean rag...then repeat with the other side. This normally leaves the bag feeling a little sticky/tacky for just a bit but it will go away.
Don't be surprised if you see a little color coming off when you buff. A little bit is okay.
Make sure that you purchase
conditioner and not
cleaner.
I use Collonil WaterStop to prevent rain stain but don't normally treat my black bags. I would apply this after the conditioner has had a chance to dry.
I know that this sounds like a lot but it's worth it. It's really a one time expense since these conditioners and sprays go a long way.
Search the other forums and see what people recommend for lamb. I wouldn't recommend Leather Honey...but that's just my opinion.
*Don't put Fiebing's Edgekote on the handles. Edgekote is a heavy sealant. A lot of people used it to treat the older Roccos that don't have the improved piping.
