Hi, Scott. I have not used it and the books I have on strippers don't list it. That is not unusual as new strippers appear from time to time. Please let us know how it works.
Removing paint from brick is always going to be a nasty job because of the way the paint gets down in the cracks and crevises of the brick. If ks3 is methyl chloride based, it will work faster than Peel Away but be more dangerous to be around. Most knowledgeable people suggest an organic solvent respirator with methyl chloride in addition to chemical resistant gloves, eye protection and long sleeved clothing. Be sure to follow the instructions on any container of stripper.
