Go to Amazon and search for adhesive backed neoprene. It comes in 6”x6” squares. It’s primary purpose is to deaden vibrations on things like washing machines, where the pads are stuck to the feet of the machines. Anyway, the pads come in thicknesses of 1/8” to 1/2”. When you buy that get a roll of adhesive backed leather tape also sold by Amazon. It’s to repair leather upholstery. Place the neoprene pad on the comb and cover it with the leather tape. Looks acceptable and works great. I’ve used this method to build up a Parker and a Perazzi. I cut the pads about 2.5” to 3” wide (depending on comb width) and 5” long. Adhesive is tough but it did not harm the poly finish on the Perazzi.
