Lacquer or Poly
I'm making a couple planters for LOML. I used Gorilla glue and need to use a good top coat. I'm trying to decide if I should use an oil base poly or lacquer.

The planters are mainly for inside use but the plants will need water from time to time.

Won’t really matter for the exterior though lacquer is hard to find these days.  Unless it’s waterborne.

Won’t really matter on the inside either since the soil and water is going to destroy anything short of epoxy.  Best to get a liner that’s waterproof.
I did a very similar project just a few weeks ago for a family member. Two boxes made of walnut. I made them with a pull-out tray for excess water to drip into and covered the interior with fiberglass mat and painted the outside with fiberglass resin and a couple of coats of spar varnish for UV protection. The walnut color and figure shines through nicely and they are well protected from moisture. So far so good.
Lacquer dries hard and won't be very flexible for an outdoor application, where there would be a lot of expansion and contraction. Your lacquer will get cracks and end up a mess. I'd use marine varnish or something rated for outdoor use.

No thought about - poly.  I like the ease of lacquer but poly dries pretty fast now.

Always use the right tool for the job.

We need to clean house.
