Don't chuck that sideplate Brian.I got this '59' grizzly and it had some bad tape marks on the grip leather.I used some "Basics" acrylic,artist tube paint in "sienna" color and painted over it.
Basics is a budget acrylic paint.I bought it at Michaels craft store.Our Wally World used to sell it.The sienna in other brands is not the right color.
It may sound wierd to paint leather but understand that this paint soaks into the leather and dries as a very flexible vinyl like film.I have restored sideplates and handle leather on '54' and '57' Kodiaks and this Grizzly.It blends in well and wears well.I imagine it makes the leather water resistant.Acrylic paint,though water based,doesn't rehydrate once dry.
I wish I had a before picture of this bow to show you.I made the sideplate and colored that with the same acrylic.
