Dan, you said earlier that you had some bubbling when 'mixing' finish layers, and had to start over? Just wondering if you could give more details about which products did not get along? If I missed it in your posts, I'll go back and re-read.
Hopefully it is something you can share to help someone else possibly avoid in the future.
I feel it would definitely NOT be a slam against any single product, just a caution to avoid mixing two of them.
