Thanks for all of the replies and discussion everyone. I have sanded down the doors. At approximently 1 foot past the door handle the basecoat starts to feather and stick properly. I can't find any loose paint outside of the door handle area (for both front doors). However, for a two square foot area around the handle, the paint has peeled off in sheets.
I use lint free disposable towels for wax and grease remover. They are not cloth and do not get washed and are in a "sealed" box until use. I do not use any fish eye eliminator and have never used any, or ever had the need too.
I have activated TCP's paint with SPI activator on three vehicles now with no issue, so I do not think that is the cause. Something getting under the paint seems like the logical cause to me as well. Maybe the temps and humidity was just right to not let the waterborne completely dry. I will be reshooting the doors this weekend and I am going to allow for additional dry time just in case.
I keep all of the chemicals in their original bottles. I mix up a quart at a time, so if I did mix in the wrong products it would have affected the entire doghouse.
I will re-read this thread a bit later when I have more time to try to understand all of the discussion. I will post an update on how it turns out and any other details I can think of. I appreciate everyone's effort to figure this out and Barry's offer. I still have plenty of supplies to finish this.
