Funny, scotchgard has quite the brand recognition. I was generically answering a protector application question. Didn't think about the actual product being applied.
I talked to Larry Cobb a few weeks ago about all his protector products. I have been using Ultra Seal for years, it is his premier product in his line. At the price point I spray it on everything - Tile, stone, carpet, and upholstery.
Thursday I visited Tom Forsythe's office and picked his brain on protectors and the different product lines he carries. Interlink has a really nice line of protector products. Tom has a water base protector for upholstery I'm going to be playing with. It was designed for the new EPA VOC regulations. Visiting Tom was awesome, His wealth of knowledge can easily flow right over my head (which isn't that hard).
A few things I took away from those visits with Larry and Tom. Both have great products that would be much more effective then Scotchgard in their opinions. I feel competent in trusting both their opinions. I've never tried Scotchgard and don't see myself trying it.
