I love CPR. It is my basic conditioner I use for all rehabs. I find it to be thicker than Bicks. I don't think you can mix paint with Obenaufs; she probably meant Obenaufs oil.
I would only order another leather product if the ones I had weren't working. I've tried Leather Therapy and I don't see why people like it. At this point, I'm trying to use up all the half empty bottles I have, no matter what the brand.
I usually mix paint with Lexol as it is a thinner conditioner, making it easier to spread. I guess it would work with CPR. A lot depends on the purse. I've had excellent results with pebbled leather. Glove tanned is trickier. For that, I only do the corners. Anything else would be noticeable.
I will try the CPR first since I already have it and if it is too thick, I could try using the Bick5 since it is a little thinner. Glad to know I have enough products for now. Thanks for the advice!
