I have alot of older silk flowers that I would like to use outdoors this Spring and wonder what I can coat them with to make them water proof and non-fading? I saw a product advertised in an old craft magazine that was called "Shine Master" made by Design Master's Co. I wonder if it is still available and if anyone has used it for silk flowers?Or does anyone know of another product I could use? I have tried a spray-on acrylic but it didn't work very well.
