One other point after I re-read your post....the roller spews the dye out the edges after it's saturated and you can NOT HELP BUT GET STREAKS....since it spews it out in a line on both sides of the roller....you have to address that or those "thicker streaks" will remain....... So....since you're already at coating 1.5 ish...I would NOT use the roller....the terry sponge thing did far, far better.
