Even just using wax on wood can give you something like this after sitting a cold drink on it.

The best way to avoid something like this with cans is something like this

With glasses would be an insulated glass.

That is the purpose of a coaster though, so your table doesn’t get damaged.

is the ‘rattle can clear gloss stuff” lacquer?
personally i use oil based poly. the ones i have on my tables get used a lot and have been active for 5 years.
satin finish,though. that hides the wear they receive.

No finish is the best finish, or oil. The purpose of a coaster is to protect the tabletop by catching condensation. If you apply a hard finish the water will puddle and either run off onto the table or stick the coaster to the glass so when they pick up the glass the coaster falls back onto the table. It’s why coasters are usually made from cork or absorbant stone, stuff like that.

Rick-M makes some good points and one of my wife’s biggest objections to smooth topped coasters. Without using some sort of absorbent material on the top to deal with the moisture there needs to be a rim and or a engraved relief pattern on it to channel the moisture and leave a vacuum break between the glass, moisture, and the coaster.

Aside from those complaints I would suggest using a hard salad bowl finish from Behlen’s or General. They call it “Salad Bowl finish”. It is a wipe on product I use on, you guessed it, salad bowls and other small items. Four coats is impervious to moisture, alcohol, and oil….at least for several hours, and it is easy to wipe on with a soft cloth or high quality paper towel. I’m pretty sure it is a polymerized lacquer of some sort so once the can is open you need to reseal it and remove the air (use one of those nitrogen spray cans for that) or put in a smaller container with little or no air or a film will develop on the surface. I usually repackage mine into small canning jars.

I have been using wipe on Poly on the cedar coasters I make. I have sold over 500 of them over the past three years and have had no complaints…yet. I like the idea of using an oil though.
