For 4 years I've been using the Volkswagen/Audi brand of interior protectant made by Eagle 1. The stuff works great, leaves a very low gloss sheen, smells wonderful and seems to last quite a while. I'm tired of driving to the dealership and paying $7/bottle for it but I can't seem to find it anywhere. All the places that carry tons of Eagle 1 products don't have the interior protectant in stock. What gives?
