Composite Prime & Paint solutions

Don't use smooth prime. Sometimes, for no apparent reason, it
bubbles up under the paint and oozes brown goo. Nothing sticks to it
well. See http://www.cozybuilders.org/chapters/chap25.html and read
the addenda at the end

I am aware that Zetlin had bad luck with it and your dislike of it even
though you do not indicate that you ever used it yourself.

But to be objective and fair, there are many who have used smooth prime
successfully

- including myself with the paint on for two years now. I used PPG
acrylic urethane right on top of smooth prime and it sticks well with
no indications of the paint comming off. PPG seems to stick to
anything.
