I have a new stainless steel sink and installed a Kohler sink flange following their package instructions. The instructions for putty only stipulated "apply a ring of putty." However, subsequently, I find the instructions regarding the flange for the disposal I am installing on the other side stipulates a ring "half an inch thick." The ring in a flange installation online video shows a ring about that applied to the area in opening and the flange fit into that. Other online instructions show 1/8" (which mine probably was) to 1/4" thick. When I set the flange, putty came out pretty much all around...but not much.
Question: 1) if I got excess all around, is it set in "enough" and 2) if not and I have leakage underneath when water is run into new sink, is it set "permanent" or will it release fairly easily once I remove screws and tightened ring?
