Hello,
I am a leather repair tech. I saw your product, Prep 7.7 for blue jean dye.
I do this work for fabric protection/leather protection Insurance plans...eg. Guardsman, Guardian etc....and no one covers this type of damage, so I've never had to sweat it.
Now I picked up an account that DOES cover this damage. I was sent the work order for a cream colored sectional. Although the customer said it happened in 1 event, most people lie in order to take advantage of the insurance and have them deal with it so I would say it's probably a years worth of lying around on the furniture while it soaked in the dyes....so I see your product, and it's speaking about dwell time......How much dwell time? Since I perform home visits I can't be there for hours dealing with this.
Thanks,
Sal
