Do-it-yourselfers often have difficulty removing paint stains without causing unintended damage to underlying surfaces. This isn't a complication if you are removing paint from a gun barrel; metallic gun barrels are durable enough to withstand a considerable amount of duress. Utilize a stripping solvent to thoroughly free your gun barrel from ugly paint stains, Take the proper safety steps before hurrying into this project.
Step 1
Unload the weapon and ensure that the safety is on.
Step 2
Carry the weapon outdoors, and place it on a canvas drop-cloth.
Step 3
Remove as much of the paint as possible by scraping it with a flexible-plastic putty knife. A rigid-metal putty knife might cause minor scratches in the metal's finish.
Step 4
Protect your hands from potential burns by wearing rubber gloves.
Step 5
Apply lacquer thinner to the gun barrel; use a clean rag. Immediately cover the barrel with a plastic drop-cloth.
Step 6
Remove the drop cloth after five minutes. Scrape the loosened paint from the barrel. Use the flexible putty knife and coarse sandpaper.
Step 7
Clean the gun barrel with lacquer thinner and steel wool. Wait ten minutes for the thinner to evaporate.
Warning
Cover the barrel with a drop cloth. The lacquer thinner might dry before it has an opportunity to loosen the paint.
