Default What should I use to seal the end of my port

So I want to shrink my port volume and was going to add 1/2" sections to either side of the port. What sort of material should (or could) I use to coat the ends of the port so they look like one piece. Can I use a body filler or something like glass bondo on the ends and sand it down?


Any recommendations or tips would be appreciated.

Personally I'd use mdf with a roundover bit. That would be the cleanest look

Sorry should have noted if it makes any difference. The port is made out of birch. I will be using 1/2'' birch on both sides of the port walls to reduce the volume. So you think just using glue with a round over?

Bondo is your friend, it's easier to sand it smooth before it fully cures.

So "glass bondo" would work? This will be my first attempt at doing such an endeavor so again, I'm open to any tips! Thanks for the input.

I've done it before using 1/2" pieces of mdf screwed/glued to the port wall. I filled gaps between the pieces with wood glue & saw dust paste, then sanded it and went over it with bondo, then sanded again. After I was done you couldn't even tell.
I've even thrown a whole box on the table saw and cut a whole panel off, cut the depth down 1/2", then reused the panel. Couldn't even tell. You can add another baffle that covers the whole face of the box and use a router with a flush trim bit to cut your new(smaller) port
