Hi Luis, where do you buy Airwaves Fabric Opaque ?Everlast dark is the same as Ironall dark. I suggest you search the forums using "Everlast dark" or "Everlast for dark" or "Ironall dark" or "Ironall for dark" as keyword. There are mixed reviews on Ironall dark. There was a bad batch that supposedly has been corrected with the latest batch. It did not work for me IMO because it was wearing off after repeated wash and dryer cycles. I use Airwaves Fabric Opaque instead.
Thank you. Once again I got it wrong
