Lin-Speed Penetration — There should be no other finish on the piece that may prevent the penetration of Lin-Speed into the wood. Lin-Speed will generally work fine when finishing over other oil type finishes.
Remember, Lin-Speed is meant to penetrate and fill the pores of the wood. It works within the wood with very little on the surface.
Non-Wood Parts — Remove the non-wood parts from the piece or isolate with tape. Strip off the old finish with your favorite paint/varnish remover and follow the manufacturer’s directions.
Wood Prep — Take your time with each sand paper grit. The more uniform the scratch pattern the better your finish will look.
Remember that Lin-Speed is not a varnish or polyurethane and is not meant to hide the wood with a surface coat but is truly and in the wood finish.
Scratches — Scratches can be sanded but take care to remove only a little wood at a time so you don’t make a noticeable hollow in the wood. Be particularly careful if sanding a portion of the piece where a non-wood part will be reattached for this may ruin the fit. If there is a deep gouge or other extreme missing material it may be necessary to use wood filler. The novice may want to visit a local gun smith for this repair.
Stain — Apply any color stain to the piece desired and let it dry according to manufacturer. THE STAIN CAN CONTAIN N SEALER OR POLYURETHANE.
Checkered Areas — If checkered areas on gun stocks need refinishing, apply the paint/varnish remover and use a brass brush of moderate stiffness to remove the old finish. Go easy, so as not to knock off the points of the checkering.
