Back in 2009 I used California. Paint and again

Back in 2009 I used California. Paint and again
in2016 I thought quality was terrific. So I purchased California Paint again redoing my
Home ,I am not to pleased this time because it took 3 coats of Califorian Paint t.time to cover
A yellow over a yellow paint. I paid 50 something
for this paint I thought I would get away with one coat like before or maybe 2 but it is taking 3 coats
Even the white on white. What Happened to the Quality California paint use to be it is the same as
B.M. paint now
