A great product ? It does what it says .which is what you want .
Excellent product. Does what it says no messing. Very easy to apply. My Mum is very pleased with the results. Water now beads off her imprinted driveway. Though it is worth noting, the brush purchased. Still shed when used, which is a pain, even after several minutes of attempting to rid it of any loose bristles beforehand.
Good stuff. Should have bought more the first time but now all done and looks great
