Thanks for the suggestions.
I did visit Geocel's website and was surprised to see "The white is listed as having higher adhesion"
The blue tape worked OK on the molding but I wasn't able to use it to good effect on the upper edge. The Geocel product skinned so fast that I couldn't blend it to the tape, and it pulled when the tape was removed. Hopefully I'll find a good technique. Maybe it will be easier in cooler temps with FL's higher humidity.
I also hope this product bonds to itself. There are places where it shrank or flowed down that now need to be overcoated.
