Need a gun for restoring factory look of sealant.I have 2 options as you will see in pics.
The one with the top tube for the cartridge and the one with inline cartridge and air nozzle.
A friend is using the 3m inline one and advised me that one is the best for narrow stripes.
And another problem with them:
1'st one with top cartridge uses air to push the cartridge piston and air gets inside the tube??
2'nd one uses air to push the gun piston that pushes the cartridge piston,and air should not get into the cartridge.
Experiences?
Thx,
