Let me save you all alot of time and exercise RIT liquid dye in dark green at 180 degrees and white vinegar and a squirt of dishwashing detergent didnt do anything to my awning. I followed all the youtube directions i roller brushed it pumped the liquid dye directly on it with a sprayer lt turned green i let it dry got up on top of the box to wash off solar panels and washed every bit of the green rite off like water on a waxed hood sooooooo im going to try the rit synthetic dyemore later this week ! If that doesnt work looks like 383 green will give me some color on it . KNOCK ON WOOD
