This is why I shouldn't attempt to rehab light bags, I am never happy with the results! Recently I picked up a white legacy zip in very good condition at a garage sale for $8 (AT link below).
I washed it and it came out much cleaner but still dingy-looking with some scuffs and signs of wear. It took the hangtag to JoAnn's and found that "warm white" acrylic paint was almost a perfect match straight out of the bottle.
I mixed paint and Leather CPR and spent a lot of time painting the bag. I came out much whiter but it looked a bit chalky to me, yet it still didn't cover the flaws as well as I would like!
I probably used too much paint and put it on too heavily. Maybe multiple thin applications would work better?
I scrubbed the paint off and rewashed the bag and it is soaking in rinse water right now. My husband said "isn't that the bag you've spent all this time painting, what the heck are you doing?!"
What a pain, I should stick to dark bags as rehab projects!
