The young guy next door has built a vibrating tank which will be filled with some kind of ceramic beads or stones to polish parts that he will coat with some kind of ceramic coating. He needs to line the tank with some kind of rubber or soft plastic so the tank doesnt wear out prematurely. Does any one know what works, cost is a consideration.

Here is the process, polishing starts at 4.08

Spray-on "Rhino liner" works. Not as soft as commercial tank liners but we have used it with success on vibratory feeder bowls and tumble tanks.

I vote for looking into sources for urethane rubber.

I have not formed with urethane myself but I have used products that have
been molded locally by others and have been impressed by the versatility
and durability of this material.

I think that with a system of oscillating/rolling the vibrating tank with a
suitable fill of uncured urethane inside until it sets firmly, your neighbor
could achieve a thick uniform coating throughout the interior of the tank.

Devcon makes a two part urethane material in different durometers. I used it to line a hexagon tumbler with good results. It never chipped or wore through.
It is pricey though.

My tank is U shaped (100 lb); I use old conveyor belt cut to fit. I use a ceramic media and water/soap mix. Belt lasts a very long time.

And if you want cheap flat belting, look for cheap/free used treadmills.
