I restore Bakelite knobs using the same technique I use in restoring Control
Heads (trafficator) units.
The below descripption is a bit overly simplistic and misses a few
First of all I typically clean the bakelite part with warm soapy water and
#0000 steel wool, which is very fine. Also, you don't go from 400 grit
sandpaper to 1000, that's why they make 600 and 800 grit. In fact I
typically start with 280 or 320 grit (if the surface is very weathered and
rough) and progressively sand to 1200 grit. As stated below, 400 grit is a
good stating point for most applications.
I use a special leather dye plus black shoe polish AND I then still buff to
a high shine (just as they were originally) with *"Dico"* plastic polish on
a buffing wheel. The white lettering can be put back in with white *
"Testors"* enamal model paint. Finally I apply a good Carnuba wax.
The results CAN look as good as the originals. I know since I have compared
them to an NOS pair of WIPER and HEAD LAMP knobs that I have for my BN1.
