I am new to rehab as well. Based on my experience with the Leather CPR, I'd say, don't afraid of the scratches, especially on dark color bag. It will be gone after you use Leather CPR on it.Rehabbers, I have never ever rehabbed a bag before but I’m considering a bag with many scuffs. How hard would it be to get them out?
Specifically this bag (please don’t buy it until/unless I pass on it, thanks)
