I also use black insulation tape, same as RickF, I got the tip from Bryan Young, I think it works well, for me the best yet.
I lay my planks down on double sided tape, the deck marked with the planking shift - length of the plank divided by four, and each plank advanced by 1/4, so that every fifth plank lines up with the first.
Also on the insulation tape, I leave a few mm spare at the end, which I fold round for the butt.
Very, Very tedious, but it really does look good.
