I've used the flattening product for Interlux Interthane, (their
prior-generation LPU) and I roll&tipped it. It sorta worked, but the gloss
was uneven.
I'm now involved in an Awlgrip job and the Awlgrip tech support folk said
that the flattener stuff was intended only to be sprayed. When pressed
about how to apply by roll&tip, they suggested trying a very thin coat,
thinned hard with MEK.
I finally resigned to applying the stuff without adulteration and will knock
the closs down with various abrasive methods. That'll be a last chance to
deal with the inevitable boo-boos in the paint.

Certainly over-thinning a top coat of varnish dulls it considerably.

Hi all,

I'm going to be painting the cockpit sole and cabintop of my new
catamaran cabin for the first time. For the glossy areas (sides of
the cabin) I'm going to use Devoe's 2 part polyurethane. I know it's
not as shiny as Awlgrip but that's o.k. with me.

For the non-skid areas I'll use Awlgrips coarse non skid particles
mixed and sprinkled onto the wet paint. But my question is this:

how do you make 2 part polyurethane flat? I've used a very expensive
flattening paste when painting with Brightsides. I suspect it was
mostly clay. Anybody seen a flattening agent for a generic 2 part
polyurethane paint?
