Hey all!  I have a ton of garden flags, I love collecting them. And yes, I know thay are made to be outdoors but they do fade over time. I had heard that if you spray artificial flowers with Thompson Water Seal in the spray can (found at Walmart around here) you could put them outside. Do you think if I sprayed a light coat on my garden flags that it would help protect them more? Do you think it could hurt? Thanks!
