shocked no one said p21s yet pro's- super gentile, nice suds not too much, doesn't strip wax, no over powering smell. con's- expensive, only small bottle I love this stuff.. it doesn't strip any wax and it suds up nice with larger suds instead of a million small bubbles. Swissvax car bath I LOVE this stuff. pro's- suds up well and the lubricity is awesome, the smell is great and it leaves the car feeling great without stripping wax when not tripling the recommended dose cons- expensive, only in small bottle's 250 and 500ml i believe, says to use such a small amount(2 cap fulls) i use 3-4 without stripping wax..if i use 1-2 not enough lubricity.. the caps on the SV bottles are super small.. and if they want to use cap sizes why have a pressure top which snaps open to stream out liquid? but this stuff is awesome..probably my favorite shampoo with p21s a close second..i really love this stuff b/c i never strip any wax of with either..for that i use cwg.
