True, if you are countersinking without plugging. But ipe' plugs on an ipe' deck look way better than exposed SS fasteners. Don't see how countersinking to 3/8" or so has any structural effect when using 5/4 stock or better. Trimheads seem best.If countersinking and plugging is normal in NC, I hope the builders are getting a ton of $. What a tedious, time consuming job.
Why would you want to "undo" a countersunk and plugged ipe' deck? A light sanding is normal for us when first prepping ipe', whether stripped or unfinished, plugged or not.
