When caulking around a bathtub, or over any type of seam, the best way to get clean lines is to use a little masking tape.
Note: If there is old caulk that is dried out and peeling away from a seam remove it before applying new caulk.
Once the seam is ready to be caulked, apply masking tape to either side of the seam such that you create a gap for applying the caulk.
Now apply your caulk with a caulking gun.
Next use a moist towel, or finger, and run it down the length of the freshly caulked seam.
Allow the caulk to set up a few minutes, and then peel away the masking tape.
With the tape removed, you will have clean lines that are uniform in width the length of the caulk seam.
