Steering Wheels
Hi Tom,
My perception is that the only steering wheels you see in car shows with graining are those wheels that have been "restored".
I am glad someone else has experienced the same doubt that I have for so many years.
My understanding is that the base plastic moulded substrate of the wheel is a grey color, and that the top coat is a fairly thick layer of enamel paint with hardening agents. I would guess the wheel ring steel was originally placed in a 2-half form, the plastic added, cured and removed. However, I can find no evidence of a mould line for the 2 halves - perhaps this was sanded smooth.
For a restoration, I'd guess one takes a triangular file, painstakingly notches each crack, fills in the notch, sands to restore the contour and finger impressions, then paints it. Of obvious concern - can the repairs be seen through the paint?
Ah Ha! Enter the textured coating. If it is spatter painted on the wheel prior to the finish coat, the peaks can be knocked down much like the hopper gun application of spray-crete to create the grainy and raised finish, while adding mechanical strength to the repair coat below, and while hiding filler lines which may result from shrinkage over time.
Thant's my theory. All I know for sure is that my blue 58 wheel looks like heck, and there is an obvious reason why it is the last thing that the restored car needs to have done.
Regards,
Jack
