The first step would be a thorough 2 bucket (strip) wash, then usually claying with lots of lubricant. Then you usually move right into polishing (although some re-wash). If you are doing all this in the same time frame (at least the same day), under most circumstances you should have pretty clean paint at this point...there should be very little to no dust on the paint. So, after polishing if you gently do an IPA wipe-down with a clean, soft Adam's single or double soft MF towel...I would think it would be pretty hard to scratch the paint. I think if you have clean paint (no dust or dirt) you are pretty safe in gently wiping with a quality Adam's MF, whether it be an IPA, with detail spray, or waterless.
Am I thinking correctly?
