Several people have mentioned using hypodermic tubing to simulate decking plugs. Some with greater success than others. I gave it a try, first with 24 gauge (.022" O.D.) then 20 gauge (.035" O.D.). While the 24 gauge may be closer to correct scale at 1:48, it was too small to even notice. The 20 gauge works out to 1.68" at 1:48 scale. Someone may want to try 22 gauge. I sharpened the outside edge and twisted a pin in the end to eliminate any burr on the inside (per Ed Tosti's suggestion). The burr would have caught the "plug" and pulled it out. To stabilize the tube while tapping with a small hammer, I glued it into a hole in the end of a small piece of doweling. I suspect occasional honing and de-burring will be required. There is a very small learning curve to get an appropriate plug appearance. I've not tried it on darkened or oiled deck material (the plug may become invisible) but I think it works well on light colored decks. One question: When you cut off a piece of the tubing with nippers, you crush the end. That means you only get two tools from a length of tubing. How do you cut it without crushing the end? Will a jewelers saw cut the stainless tubing?
