This thread , got me thinking and figuring and low and behold a small project ensued
First I examined the OEM grips on my Cimarron ( reposted photo )
I determined it is Yellow Meranti Philippine Mahogany.
It is a hard wood with relative hardness equal to America Cherry and bit under Black walnut, both woods common in gun stocks.
It is noted for strength and durability and heavily used in flooring...
The grips have finish , I believe a varnish and if you want to darken your grips this will have to be striped ...
After 6 years of moderate use , and Abilene pointing it out I decided I did want to refinish mine .
No sanding !
I use Homer Formby's Finish Restorer ( it's mild stripper ) and soft brass brush ( looks like tooth brush )
The Gloss finish comes loose quickly and completely, next I use the same brush and acetone which dyes rapidly
and leaves the wood bare and open to stain , in my case Minwax Wood Finish, Dark Walnut.
dip the grips in the can, allow to drain on a paper towel and dab dry the checkering. Allow to fully dry over night
I then use Johnsons finish wax.... applied with piece of Khaki cloth
