not quick but effective
Takes a LONG time to "burst" but, when it does, the gel scrapes off easily everywhere it has been applied. It does not have any noticeable odor but does warn (rightly so) that it should be kept away from skin as it burns. It is quite thick and I do not know how many uses I will get from the bottles. In any event, it is less messy, stinky, and labor intensive than acetone soak off.
