Hey bow, the Marlin finish is a spray on quick drying finish. It will start cracking a chip off later on down the road. Should this be a good Marlin then get it and refinish the stock, just make sure you seal all the inside surfaces as well as the outside surfaces, taek care, John.
I doubt you'll wear it off any time soon.
Mine hold up very good. I had a stock finish taken down to some stain and bare wood. Hand rubbed several coats of true oil in it also .To achieve a soft appearing glow instead of a bright shine . But I've seen
& had a few newer ones that seemed like sand-paper would'nt cut it.! I had to hire some one that was hungry to strip my stock .I had a bad arm at the time. Took a long time to get it done.
Sadly i had to pass on that 3030. I didn't pass on a 336 35 rem. Nice walnut,1970s gun. Looks in good shape. Hopefully pick it up next weekend. Had a butt pad installed at some point, but still looks okay.
