This table was in pretty rough shape, the top was missing, the varnish was flaking, and the wood had greyed in the weather. There was some discoloration I suspected was mold.

I had a scrap of particleboard left over from an arcade cabinet I helped a friend build, which happened to be a good fit for the top, so I decided to combine the two and put them up on my local Buy Nothing -type group. I sanded off the finish, posted a picture asking if anyone would like it once I fixed it up and what color they'd like it painted (normally I restain them but I wanted to get this one done quickly to clear space, and I didn't love how the wood looked (it had a lot of those zigzaggy joints they use for cheap lumber).

A couple people were interested, one picked white, and I painted it up. I laid out a dropcloth and set the table upsidedown first so I could get all the spots underneath the joints, then I flipped it and painted it standing upright.

Some of my yellowjacket buddies came to check out what I was doing but we managed to coexist. Nobody got stung and nobody got sprayed with paint.

I turned it four times so I could see how each side looked in direct sunlight, and made sure I hadn't missed anything.

While it dried, I used some white acrylic paint on the sanded edge of the particleboard, to seal up the material. Once that was ready, I flipped the top so the good side faced down, flipped the old table base so it was upside down on top of the upside-down top, measured the distance to each side and adjusted till they were even. Then I drilled through the existing holes in the base, just through the plastic veneer on the particleboard, and drove six drywall screws through.
