I have to fasten some thin teak (4.5 by 1/4 thick) to mahogany-veneered plywood inside a boat galley. It's to dress up a hole around a microwave oven. I got the teak ready, but I'm not sure I can get brads (the fastener that would match the old ones) to go through it. The old fasteners are barely visible from the outside. It looks as if they took tiny brass brads, snipped the heads off, and nailed them in. The closest thing I could find was 18 x 3/4" brads, and they don't seem to like being driven through this hard wood.
I don't want to use glue, and apart from that, I heard that it doesn't work well with teak.
Suggestions? The boat is a 1978 Hatteras yacht, if that helps.
