How to Paint Synthetic Gunstocks

Updated February 21, 2017

Gunmen paint synthetic gunstocks for a variety of reasons. In some cases, the desire is to create a custom colour or look for the weapon. Other paint jobs replace damaged finishes and give the gun a new look. The process requires a few basic tools and a knowledge of paint and guns.

Remove any gun parts from the gun stock. This includes the barrel, action, trigger assembly and guard and gun swivels. Different models of guns utilise different methods of fastening the parts together. Research the gun and learn how to remove the gun parts from the gun stock.

Apply masking tape over the barrel bed, the channel the barrel and action of the gun rests in, and the butt plate. The butt plate, or possibly a recoil pad, sets at the end of the gun stock that rests against the shoulder when the gun is fired.

Sand the gunstock beginning with coarse sandpaper and advancing to finer sandpaper as the gunstock becomes smoother. Use the sandpaper to remove any paint on the gunstock.

Fill in any damaged areas of the gunstock with automotive body putty. Sand the putty smooth and even with the existing gunstock. This allows the repair of dents or dings or the owner can fill gun sling pivots, if desired. Some synthetic stocks also have seams from the forms that can be filled for a smoother finish.

Prime the gunstock with two-part epoxy primer. Add a second coat of primer if the putty filled areas still show a colour differential from the rest of the gunstock.

Apply the finish paint to the gunstock. Apply the paint using a sprayer. The spraying equipment and the paints are available from auto body suppliers. Allow the paint to dry overnight.

Apply a clear finish over the paint to protect the finish.
