Hi;
What I use for wood decks is so out there, you may not be interested, but think about it, okay? Look for a Luan mahogany interior house door that's been junked. Out in the eather kind of. The Luan will warp off and slowly peel away from the rest. It's about a 1/16 of an inch.
What I like about this method is this. You can sand it thinner and you can you use drafting ink or tech pens to do plank detail. Also oil based pencils work well too.OF Course you must remember I work in larger scales. Now, that said, I do use wood rarely on smaller scales. Sanded paper thin, and "Planked" with a .010 tech pen.
Besides in it's original thickness it's great for planks on plank on frame or bulkhead ship hulls. And it's Mahogany so it is a little harder to sand through. But, Warning, do NOT breathe the DUST of ANY Mahogany Species. This is NO Matter how many times it's been processed. It CAN be harmful to sensitive Lungs.
