are you filling and painting the cracks in the steering wheel? are you covering it or have a new idea. not sure steering wheel non adhesive tape would look good. maybe leave it alone. shoot, thinking again.
Take a file and "V" the cracks out to except PC7 epoxy, fill the cracks then sand down any excess then follow the usual paint prep procedures. Sent from my SM-J727T1 using The H.A.M.B. mobile app
Another repair that works really well, is using crazy glue and then add baking soda ( not powder). It will instantly become hard as rock. I have seen professionals, who work on musical instruments, use this combo combined with dust of the parent material, to make super strong repairs that are extremely durable and difficult to spot.

Here is a youtube link to fix guitar frets. There are hundreds of youtube videos detailing how to use super glue and baking soda to make a wide assortment of repairs, including an emergency repair of a radiator. Bob
My steering wheel was cracked in many places, did the PC7 thing, primed, sanded and painted. Slowly the cracks are coming back. The car is manual steering, likely would have not cracked again with power steering.
I have had success with using the same parent material that the steering wheel is made from to do repairs. If you can find another damaged wheel, break off some of the plastic with some pliers and soak it some of this solvent. It will soften and melt the plastic, when the it dries it becomes hard again. It might look like a mess like a lead job, but file it down, sand, reshape, prep for paint.
I used to use MEK when I worked in a pinch valve factory in high school. Great solvent, but super carcinogenic! You really want to wear personal protection equipment when you play with that stuff.
'Crazy Glue'...('Hot Stuff') We used this a few years back ('80s) for finishing rough surfaces on what would become glasslike finishes on large scale wooden model airplanes. The 'gap-filling' qualities of baking soda were quickly replaced with much preferred 'Micro Balloons', (they look like baking soda, but 'finer'...Micro Balloons are a synthetic material, developed specifically for strength in filling; Sand smoother, yield a stronger finish.) Baking soda is a food staple, stonelike in structure, and would crack after a season. We'd buy Micro Balloons at Sheldon's Hobby Shop in San Jose. (now available on Amazon: Top Flite Micro Balloons, 8 oz., $9) 1983, My pal Doug and I were at a large shopping center in San Carlos, (great hobby shop there) Doug had some micro balloons in a zip lock bag in front seat of the Chev pickup. When we came out, it was gone. Some unsavory looking characters had been hanging around when we went in, but they were also gone, like the micro balloons. Wonder if they thought it was baking soda...or...
I used PC7 filler and after a few years cracks started to reappear. The Plymouth wheel was a type of hard rubber. Perhaps it works better on different material.
V out the cracks, wet your finger and smear MARINETEX in the cracks. Lightly sand, prime and paint.....................
