its been a while since i sprayed a complete, but have the tekna and spraying UC was awesome. fluid control i set by havin the trigger bottomed out, then turned in 1 1/2 turns from bottom. 28 psi at the gun, adjust fan pattern to knock off the corners, and about a 70% overlap each pass. 1.3 tip,too. gun about 8" from surface if i recall right.im far from a pro, but got some pretty awesome results with minimal OP-it was just in a couple areas for the most part.UC flows out nice.
id suggest shooting for no runs or OP but plan on having to color sand.
its wise to walk the vehicle with the gun empty and practice keeping the distance from the surface and travel speed consistant-a skill in its own.
not only that, practicing that helped me to clear my path so i didnt have to be concerned about anything in the way.
