The top of this railing post is rotted and the post is not easy to replace. Luckily the rest of the post seems solid. What kind of wood filler product can I use to fill the rotted out holes before painting?



I understand that it won’t last forever. If it can last a couple of years, I’d be satisfied.

          Use a high-performance 2-part wood filler. It's like automotive body filler but sets a little slower and is easy to plane/form/sand smooth after it sets. This is one brand that I like but there are many brands out there:

          I use a "cheese grater" style plane (Surform) to get it flat, then sand smooth. Works great for repair work when replacement of damaged wood is impracticable.

            Additional tip... there's a point in the curing cycle of all of these 2 part products (bondo, etc) when they're firm enough to slice with a knife or surform. You can use this to your advantage by slicing close to the finish surface and reducing the amount of sanding you need to do.
