I don't use CA on rear tires. Weldwood contact cement is the magic stuff. It stays flexible when dry, which reduces chunking. I check the sidewalls after every run and add a little contact cement to any areas where the rubber starts peeling from the rim (between rubber and rim). 15 minutes later, she's ready to go.

I also add a layer of contact cement to the rear sidewall, let dry, then press the sidewall against some carpet to pick up fibers. This reinforces the sidewall while remaining flexible. Looks bad, but works good.
