I recently repaired a steering wheel on one of my wheelhorse RJs , it had a 4 inch long chunk missing from the underside where the finger grips are. After a lengthy study of the situation I came upon a product called por 15 im sure alot of you have heard of it, Its a part A/B product. I kneaded it together and made a mold from a good section of the wheel applying oil first so it wouldn't stick to it. I then let
it dry for a hour,after removing the new formed mold I mixed another batch oiled the inside of the new mold and placed the new batch inside of it. All I had to do was push it up into the void trim the excess from around the repair and boy howdy it came out perfect, very little sanding. thanks HANKG.
