We have a garden bench which has metal ends and then wooden slats going across - just your standard garden bench. The wooden bits were varnished, but the varnish has started cracking and peeling off.
What's the best way to restore it? I've scraped off as much loose varnish as I can, and sanded down a bit too (can do more). There are some stubborn patches of varnish, but mostly it's now raw wood.
Do I varnish it again? Or stain it?
