LOL, I didn't actually do the siliconing while in there, just cutting out the old stuff
I read in a thread somewhere Grizz mentioning a doohickey from home hardware that goes on the end of a silicone gun to make perfect corners. I found it and tried it out. I ran a couple strips of painters tape 1/4" or so on each side of the corner and ran a bead with the doohickey, and WOW! It works awesome! Perfectly straight runs, nice and clean. Thanks Grizz!
