Sorry my reply was so long winded!
I always check your Tully thread when you update so I know the project of which you speak.
I dig it.
If you are spraying then you should be fine but I would use any scrap pieces of stencil you have for a test panel (maybe to try even before you work on the cabinet itself?)
If you don't know the glue character this would be a safe way to make sure you don't have any drama laying down paint and removing your stencil.
Biggest issue might be material compatibility with what is on the cabinet already.
Make sure whatever you are spraying for your stencil art is ok to go over the clear you sealed the yellow with and you should be fine.
Ensure your stencil is well stuck down.
Spraying can sometimes lift stencils or tape.
And don't ever worry about cluttering one of MY threads at least!
