Hi Le Chat, Sorry but this made me smile,, by the sound of it he has applied far to much and once you do that it is a mess, when cutting the spout on silicone tube, don't cut it to far down, about an inch is plenty you only need a hole less than quarter of an inch or 6mm if you are metric, when applying do it all in one smooth stroke, don't lift mastic tube untill at the end of the bath, once done, wet finger slightly then lightly run finger along the run of silicone, good luck, Ray
