    I am putting eko-prime on gel coated fiberglass and aluminum parts in preparation for top coating with eko-poly.

    Using a Devilbiss Finishline 3 gun, adequate air by Stewart System standards, paint booth temp about 75 degrees, humidity is ambient (or a little higher due to damp paint booth floors) for Anchorage.

    I am spraying the primer filtered but unthinned.

    I think this might be a gun set up problem vs a product problem but I would appreciate any help you might have.

    The primer is drying with a fairly rough texture- maybe about like a cheap formica countertop as far as depth goes but unlike a piece of formica this isn’t smooth when you run your hand over it. It sands out fine with 320 grit but it doesn’t seem like I should have to resand every piece after I spray…

    Maybe related- for open areas do you shoot with the fan control wide open? also, I have the fluid control knob open about 2 turns right now.
