Does anyone have any recommendations for a good satin sealer/varnish? It's almost time to turn in my banner for the Arts Alive banner project and I'd really like to protect it from the elements. (rain, salt air, bird poop etc) She most definitely would look pretty sad covered in grime at the auction.
The banner itself is a plastic sort of material so I need something that dries well and not sticky. I'd appreciate any advise. Karin
