No my clients get sold this product as a guard, they get told that they stainguard is not a total protection against stains, but it, in theory, places a barrier between the fibre and the stain, under no circumstances should this ever be sold as a 100% product, they also get told that this is not designed so they can clean spills and stains up themselves but they shoud allways call on a cc to take the stain out properly.
When they ask how long it lasts you should never give them a definate answer but instead tell them all the usuall bumf about foot traffic and wear and tear, and depends if they spill chemical on carpets and it reacts with the stainguard bladybladybla and so on, we work on the principle of never selling this to our customers but instead explain what it does and wait and see if they want it. tell them if they want a guarantee use scotchguard system as its mainly an insurance policy and they proberbly have cover on their house insurance anyway
