what i do is counter sink screw holes by pre drilling everything, and then i fill them in either with a dowel rod or wood filler. for the seams i will use either aquarium grade silicon, or tub and tile caulk. then after a fw days drying time i will sand smoothly and paint then it looks like it is all one piece that was meant to be.
