I have my first finished bag and wanted to say thank you to everyone for all the wonderful information on this thread! I bought this bag at my local Goodwill.
I bathed this bag in wool wash and then did an initial conditioning with Leather CPR. I then moved on to a mixture of 1 T Leather CPR with 1/2 tsp Linen acrylic paint mixed in. I used a makeup applicator sponge to apply this in a small circular motion. I used this same ratio with a stiff paintbrush and sponge on the strap edges. Lastly I used Brasso on the metal.
This was authenticated on the Authentication Thread as a Shoulder Pouch from the 1987 Lightweight line, thank you awesome authenticators for your time! It was not a very drastic rehab, just needed a little cleaning, conditioning and cover of minor spots.
