Just wanted to post about my trial with flitz before buying new curtains. As you can see not too bad. Will only use them for two months out of the year and plan to use 303 protectant on them but they came out pretty damn good with the flitz buff ball. Just warm water and soap. Dried them off. Smeared flitz around with a cloth and then buffed them like I would compound on gelcoat. Worth a shot before buying new.
