Painting acrylic over polyurethane

[NilssonBaits]

I am painting a bluegill crank bait and was wondering if i can paint the fish on the primed and sealed wood, do a coat of polyurethane, then do some detail work with acrylic paints ON TOP of the first polyurethane coat and then give another coat or two of polyurethane. Im worried the paint wont stick though... any ideas or suggestions? also i was thinking id use window screen as a stencil to make the scale patters with some gold paint.

 

thanks for any help!

It might help with the physical bond of the acrylic paint if you make your barrier coat of polyurethane matte.

I would worry that the screen's holes are too small.

thanks for the info! It says to sand the polyurethane in between coats, maybe this will be enough to keep the paint on?

I have used polyurethane to seal wood, then primed and painted with acrylic paints overtop.  It seemed to work alright, however I did not use the polyurethane on the top of the paint.  I finished these lures with epoxy, so I cant say how that would work over top of the paint.  To seal the wood, I dipped the lures in polyurethane and sanded after it was dry, twice just to seal the pours and get a smooth surface to work with.
