My lab puppy chewed on my siding. It isn’t a huge area only about 3 inches wide. Can this be repaired before painting? Thanks.
If replacing the piece of siding isn't possible, you can use exterior spackling paste to repair the area. Another product that works is FixAll. This is a exterior patching compound that dries very hard.
Make sure to prime the area with a good oil based primer first. Allow the primer to dry then do the needed patching. After the patch has dried, prime the repair with the same oil based primer.
