Be sure to post back in a few months and let us know how close to
finishing you are. Suggest you look at motorcycle websites but to go
from sandcast to polished is a daunting challenge. Basically start
coarse to eliminate all signs of sand casting and go finer to eliminate
the marks from the coarser medium and finer to eliminate those
scratches..ad nauseum. Last use semichrome or mothers wheel polish.
You may wish you stuck with sandcast around halfway through.
