Can't unscrew the ring that secures the strainer to the counter. Have tried the "standard" method of pliers ends in strainer holes from above & whatever-the-name-is of that plumbing specialty tool to "grab" and twist the ring's lugs - won't budge. Have tried to "lock" pliers into position with adj. wrench at 90 degrees (wrench end against sink wall so it won't move). No luck. Strainer slowly spun when attempted unscrew w/o pliers, so removed rubber gasket in hope that WD40 could penetrate. Still no luck.
Next planned attack is to try a heat gun to ring. Anything other ideas before getting something like a Dremel tool to cut the ring off?
