can i spackle under volan without it showing?
NO. It will show up as a white spot. For some reason it does not show the green the same as the foam.
so what can you use to fill a small hole?
where’s the hole?
How big is said hole?
You can take a small chunk of foam and patch it in. But you’ll still be able to see the outline if it. But at least it will look a lot better than spackle.
