How would you fill this hole?

Take yer minds outta the gutta!

I have a porch pillar that has a rotten hole. The rest of the wood looks good. I don't want to replace. Just patch and paint, as the house will be going on the market in the next couple of years or so.

So I was thinking of these options:

1- Fill hole with foam weather spray, sand down, then fill in with auto filler, then paint.

2- Patch hole with a fiberglass repair kit from the auto body shop, then fill with auto filler, then paint.

Any other better ideas?

You're going to need to harden that wood around the hole...Remove all loose wood, soak it in wood hardener really good...THEN proceed with what a few of the others have suggested

Yeah, good idea Geezer. Remove all old soft wood, coat raw wood with penetrating epoxy. Fill with thickened fiberglass/glass fibers. Sand and paint. That will last long after you leave.
 
I honestly had the same issue on a house I flipped....... did the spray foam and bondo method........ it was a ton of work to make it not look like ****! Good luck

Before and after. The Durham's stuff was crap, for me, and was a waste of time.

I fixed it with a 3 step process:

1- Built up a wall with Spray Foam Sealant (yellow stuff).
2- While the Spray Foam Sealant was almost dry, I put on an aluminum mesh square to fit the size of the hole, then made it almost flush with the column contour.
3- Applied O'Reilly Auto store bought auto bondo! This was the greatest stuff to use. I also used the bondo on other bad areas of the column.

Once sanded, I applied primer/paint and here it is.

That's what I would have and have done. I'd probably use wood hardener after removing the rot but other than that looks good to me.
