I am using Fastcap double sided tape on my current dining room chair project. My template for the back legs has to be applied to each leg blank for routing to final shape. It holds well and can even be resused several times before being replaced. It is also thin. When I separate the pieces, sometimes it pulls a bit of the top layer of the plywood template but does not damage the workpieces. There is a small residue on the workpiece but it comes off with sanding and isn't enough to gum up the sandpaper. The back slats (6 per chair) also get template routed so I've been doing this a lot (10 chairs). The residue on the template of the tape doesn't come off real easy but it does come off using a knife or chisel to scrape it away.
