I'll be repainting my Mom's house soon, probably with Sherwin Williams Duration. However first there are some holes that need to be patched.
Birds (I think they are mostly grossbeaks) have pecking/ chewing holes in the siding and stuffing grubs inside. Watching them closely, I am quite sure they are not woodpeckers and are not feeding on bugs that are already there. They are using the siding for a larder.
They are pecking the holes along the bottom edges of the shiplapped Western Red Cedar Siding. The biggest holes are big enough to stick your thumb in.
What is a good material to use to patch those holes? I'm thinking bondo might do the trick.
