We talked to the local PPG rep, and he said to resolve the issue with it lifting the 2K clear on the feathered edge, I would need to add hardener to the MBX even though it is not called for. Without the hardener, even if you build up several dust coats, the first medium coat will saturate any base it is in contact with and keep lifting the clear. Without the hardener, the 1K is not an effective sovent barrier.

Shot it last night with the hardener and it worked like a dream. I am sure there are some people who can shoot MBX day in and day out with no issues, but for me the hardener makes the stuff a lot easier to work with especially if it is metallic.

This job is finally done. Thanks to all for the advice.
