Re: sanding primer
Posted by Howard on Jun 13, 2005
when working with the primer...you should sand almost all of it off. its purpose is to fill minor pin-holes and other small imperfections..not to to take the place of good hull prep.
the other reason you want almost all of it off is that it is not a good backing behind paint that is exposed to water. Primer is relatively soft...and if you scratch the paint...the primer layer will absorb water and flake.
So again...when you have done it right...you will only see the primer in the smallest of holes and imperfections...and clear epoxy for 95% plus of the remainder.
