I just started spaying with my Seal-Rite Unit. According to the manufactors specs my unit is setup right. Tip, pump pressure, etc. The problem that I'm having is that I'm leaving what apears to be streeks. The only thing that I can think of is my pump pressure is too high and I'm getting too much material on the edges or my coaltar is to thick and needs thinned out to get a more even flow. I'm open to any and all suggestions thanks.
