Default Bottom Paint Half Price (Serious Question)

.... But what you did is an illusion. You
added volume by adding thinner. This will not harm the paint but it
will reduce the thickness of each coat as the excess thinner will
evaporated of sublimate resulting in a thinner coating than if the
paint had not been thinned. What it amounts to is you fooled yourself
into thinking you had more paint while all you really accomplished is
making extra work for yourself in that you have to add at least one
more coat to acquire the thickness you would have had with fewer
coats using paint that was not thinned ...


I'm not sure "illusion" is a good description of my thinking. I am aware
that I am covering the same surface area with less active material (in this
case somewhere between 72 and 75% of the cuprous oxide active ingredient I
have applied in the past). The question is: "Will this attempt to cut
expenses result in satisfactory single season performance for my particular
application, when compared with standard application methods?"

Can you comment based on your own experience?
