I would use wood filler which might be stainable for patching OR epoxy putty for larger structural defects. I prefer epoxy putty to bondo.

Epoxy putty—my go to miracle repair tip is the Oatey epoxy putty stick. I find it easier to work with than bondo and this clay like putty can be sculpted and fill defects. It does harden in a few minutes and will dry a gray color can be sanded or drilled and will needing painting unless its final gray color works for your repair.

This Is a two-part epoxy sticky-found at big box hardware stores in the plumbing department near the pvc purple glue. In a clear plastic red capped tube. I get mine at Lowes $6. Home Depots its version and JB Weld is another but more $ and smaller. Other smaller 2 part epoxy sticks options can also be found in the boat marine and wood repair shopping sections.

You mix -press -then you can use scrape off excess (I use depleted gift card) and/or sand and paint. Cured putty is strong enough to drill through.

Putty safely seals/waterproofs for plumbing boat repairs.... Ive used it for exterior entry door frame wood rot repair, elliptical pedal repair, multiple arts and crafts repair of damaged pottery- wood -ceramics, plug up holes in planters, repair cracks in planters or make a new lip on the pottery planter. Ive repaired holes in a utility garage sink ( thanks previous HO) repaired a break in the top rim border of an elliptical peddle, repaired damages in a concrete statue, fixed a split wood disk on a wind chime, missing part of wooden candle stick-its a great defect filler, structural and strong.
