so you're saying micron optima will stick to the plastic body of ST40 paddle
wheel?
if, yes, I gonna give it a try. you just won't believe the eco system that
lives in the paddle wheel after 1 week in water!

It probably will once the barnacles have roughened up the surface. It
certainly sticks moderately to _old_ fibreglass without primer, as I
keep on finding out when I try to paint in a hurry.

A possible problem is that Micron Optima has an activator and a paint
component with a limited shelf life once mixed.

Also I note from the posting that power boats may come into the equation
in which case Micron Optima will erode rather quickly in some
higher-speed cases.

TVMIA.

Try reading the cans or asking the manufacturers....

e.g. International Micron Optima is water based (emulsion paint) but
expensive.


A clue is the drying times look more like 24 hours than 12 hours as the
water has to dry off first before the paint starts to cure.
