Why do people spray paint guns?

Many people have a tendency to want to make their guns look unique and cool. Unfortunately, many of these people end up painting their guns, which can lead to a lot of problems.

One of the major issues is that if the gun becomes wet, the paint will peel off and require further refinishing. It can also cause rusting because it will get in between the metal parts and damage them.

Do I need to clean my gun before spray painting?

Having a gun filthy with oil and grease can cause problems when painting because overspray will stick to this substance rather than the metal of the firearm itself.

Reasons your firearm coatings don’t last

It’s no secret that your firearm will always be an expensive investment. This is part of the reason that it’s so important to take care of it.

One way to do this is by routinely checking your firearm for rust. It may seem like a quick and easy task, but don’t let yourself get too complacent about this!

Your firearm coatings don’t last because your barrel bore is not clean. A clean barrel bore yields a barrel that is less corrosive, which means the finish on the outside of your barrel will last longer.

Your firearm coatings don’t last because you overheat your gun cartridges. You can avoid overheating by keeping your fire rate at lower levels, giving the cartridge time to cool off in between discharges.
