A word of caution regarding canopy tinting using the Rit dye method. I ruined a Somethin' Extra canopy by using water that was too HOT! I tested the water with a candy thermometer and when it read 120 degrees centigrade, I slipped in the ole canopy. When I checked on it ten minutes later it looked like a week old orange peel.
I now believe that it is the time that the canopy is in the solution and not the temperature of the solution that results in the tinting action.
However, never fear; if you should happen to screw up and warp the canopy, SIG will be more that happy to send you a new one for the very reasonable price of $18.95 plus $6.95 freight.
