I want to refinish a cabinet that I will paint, so the filler I use does not have to match color. I have heard that Bondo is what I need, but there are many varieties, from the grey stuff you see on cars to the home filler material that I saw in a hardware store.

What is best for filling in nicked corners and small areas of the plywood missing veneer adjacent to the edges? Need to have the Bondo able to form a corner, again in small areas.

Appreciate your help. Thanks.
