I'm about to refinish a bow that the previous owner "refinished" by brushing a thick coat of tinted polyurethane on the riser, obliterating the SN, etc. The limbs are yellowed but otherwise in good shape and the silk screens are in good shape, so i am going o try to preserve the silk screens by leaving them in place with VERY light sanding over and around them. I've always sanded by hand in the past but find myself wondering if I would make better progress on the riser , initially, using an orbital sander with a well-worn disc. Anybody every try that?
The riser is Brazilian rosewood so I'm planning on wiping it down with 91 % denatured alcohol and letting that dry before spraying on clear finish.
