How can I touch up and clean a scuffed synthetic gun stock?

A Shooting Times reader asked for some advice for touching up a synthetic stock. Rifle reviewer and stalker Bruce Potts has some useful tips.

Q: How can I improve the finish of my synthetic stock? It’s getting really bashed about and the finish is scratched and faded.

How to repair and clean a synthetic gun stock

A: Synthetic stocks come in all sizes, shapes and finishes, each with their preferred method of maintenance if damaged or improving a new but rough stock. (Read more on synthetic stocks here.)

Stocks that have a crinkled, speckled or raised texture are difficult to refinish unless you use some Araldite to patch up the cracks or pits. Then, when hard, you can stipple or contour with a Dremel tool to match the original finish. If you have a synthetic stock that has a smooth finish but still has a rough, unsanded laminated structure like some McMillan stocks from new, or has become badly scored from use, it can benefit from a light rub with 0000-gauge steel wool. Don’t rub too hard if it’s a painted finish, as it will work through to the gel coat below and you will have to touch up more. If it’s really rough and you like a very smooth finish, add Brasso or JB bore paste as a mild abrasive to give a perfect finish. If the surface has become lightly scratched or discoloured, then I use Birchwood Casey Stock Rejuvenator, which is sprayed on and restores the colour and finish. It’s also great on rubber grips and leather too.

Synthetic stocks can be practical against knocks and scratches and keeping a rifle’s zero from shifting as, unlike wooden stocks, they don’t warp in bad climates. However, the finishes on some makes can be very rough, even from new, and damage in the field occurs easily.
