Thanks for the comments.
My thoughts were to use water based, like Glamour II. I usually do 4-6 prints one day a week, let them cure/dry/stabilize for a day, then coat, followed one evening in the week with stretching.
Agree with the comments on laquer and Dan has a good setup since he has the capability of using the other tools in his wood working business.
Just appears to be a slightly better/more consistent approach for coating when you are doing more than one at a time but don't have the spray alternative.
