Joeshmo, use two rollers, one for paint and one to level and knock down the bubbles.
I didn't mix 1-1 but used a screwdriver to stir after adding thinner. I'd stir then lift the screwdriver out of the paint and count 1, 2, 3 etc watching for when the piant coming off the tip went from a stream to drips should be around a count of 8 this worked well for me when I did my truck.
