Naaaahhhhh...it's nowhere near the 'winter project' scale.
Maybe we overdid the 'more work' part....but by that, I mean a couple of evenings to fill, let dry, sand, repeat. The second fill/sand will have it like a baby's bottom. Another short evening to fit & bed, and a couple of coats of paint...that's about it!
A week of short evenings (mostly to allow drying time) and you'll have a nice stock.
I did mine in flat black stove paint, with black 'Krinkle' paint on the areas that would normally be checkered. All I've ever done in 20 years was touch up the paint. I also bedded a chunk of wood inside the butt, to allow a screw on recoil pad. I needed the extra length to accomodate my gorilla arms.
