protec gear pump, I am having trouble with the spray pattern and coverage, i am finding oil based is much different that CT. When I spray, I believe we call it a fan, at the top and bottom of the fan I have a solid line, and inbetween the solid lines is bubbly airated sealer, it takes a couple passes to cover the asphalt. I just picked it up yesterday and was told the everythings set perfectly. but it doesnt seem to be. perhaps pressure is too low?
