Use 100% clear silicone. Cut the tip on the tube at a 45 degree angle
about 1/4 inch from the tip. Clean the old surface well and make sure
it is dry. Use a small amount of caulk in the crack and then run your
index finger down the caulk. Let set for double the recommended time on
the tube.


I really stunk at caulking until someone added an additional tip to
the above advice:

Keep a cup of very soapy water handy to moisten your finger tip before
running it down the caulk bead. A clean moistened with soapy water
fingertip seems to make a world of difference in making a smooth
bead. And of course, making that bead within seconds of laying it
down out of the gun. Some caulk sets up pretty quickly and becomes a
mess if you try to smooth it afterwards.

YMMV, but this really helped me.
