a few years ago I purchaced a Boli aluminum patio set(table, 6 chairs,2 foot stools) Overall have been very pleased with the product. However 4 plastic inserts for the chair legs to prevent deck scratching have broken, fallen out, and 3 have been lost. Recently had new cedar deck installed and don't want to scratch new surface. Do you have replacement inserts? As well, some random fibers in the weaving have turned white(Navy Chair color); is there a treatment to restore close to original color? Thank you!
