when it warms up in the spring i plan on spraying bed liner on my rocker panels. A couple weeks ago i bought a paint gun with a 1.8 mm nozzle becasue i removed my flares and need to do some body work too. well my question is will this paint gun work for spraying in bed liner.

 

IMO No. I have tried before and it does not work at all. The nozzle is way to small to spray the thick bedliner. They do make some guns specifically designed to spray bedliner, I believe even Duplicolor makes one that is rather affordable. You can always buy the bedliner in a spray can, or roll it on nice and thick.

 

what about an under coating gun?

 

Yea I would think that would work fine. Same idea, just try it out before you shoot the truck.
