American Flag Pallet Project

Submitted to Community Café

Hi! I just finished this American Flag that I made out of an old wood pallet and I brought it back to life by deconstructing the pallet and making it into this beautiful Flag that I am extremely proud of. The red is the beautiful Rustoleum Gloss in Colonial Red and the blue is the gloss in Navy Blue. For the white I used some paint that I had leftover from a previous project. My question is, should I put a protective coating on this since it will be displayed outside of my home? I am so afraid of putting anything on it because I put my heart & soul into this project. After posting this picture on my Facebook & Instagram it has now turned into a small business because I have received requests from friends and family for me to make them one as well.  Should I put a base coat on the wood for my next one? Any thoughts or suggestions are welcomed and appreciated. Thank you!
