Follow up question for painting and decorating outdoor furniture

I had asked everyone about painting some outdoor chairs that are neutral in color with a plastic waffle weave seating. Ive painted them and will post the how-to pictures as soon as I finish the table that goes with it. I have a question about the table: if I decopage scrapbook paper onto the table top to add color and charm, is the mod podge humidity and temperature resistant? The table is on a covered porch, so it does not get wet. But the heat and humidity are fierce this time of year in Georgia. I appreciate your help and thanks again to all that helped me decide how to redo the chairs! :)
