=EF=BB=BFHi: A friend of mine who is familiar with rotary engines, and also i=
n the racing,told me that he lapp his end plates with =E2=80=9Cvalve grindin=
g paste=E2=80=9D
I thoughts that i gonna give it a go.=20
So i used some old endplates for practice and experimenting with fine grit v=
alve grinding compound ( waterbased).
It actually came out,very good with  little =E2=80=9Creaching and markes=E2=80=
=9D ,of the  old side and corner seals.
This was only about 5 to 8 minutes of rotating with the hand,with only the w=
eight of the plate, and the fine grinding compound.I know that the 2 faces i=
s not =E2=80=9Cmatch mates=E2=80=9D but the surface is 200 % better off than=
 =E2=80=9C just as it is.
I believe there is still sufficient chrome coating left as you can still see=
 the old corner seals =E2=80=9Dpath=E2=80=9D against the light.
