Hi, I just finished all 33 top bars with the guides inserted into a cut groove down the middle. Now I'm wondering if maybe they may hang down too much. The guide sticks out 1/2 an inch. Should I remove some of the guide? Also, do you think I need to fill in the grooves on either side of the guide? (I'm worried about places SHB may try to hide.) It would be quicker to use a caulking gun, but is this okay for use near where the comb will be? Thanks in advance for your response.
