I feel like a complete dummy for asking but I purchased the cup liners and was wondering if I’m supposed to cut a hole in the liner or cut the whole bottom out or what to do.
Also does anyone know what the hardest clearcoat finish is? I am restoring a delta unisaw and want to make it scratch resistant.
Thanks guys.

I thought those cups were liners for the spray gun cups. That you placed them inside, fill up with whatever finish you’re going to use, and then take them out when you’re done so no finish actually touches the cup.

You’re talking about the plastic “baggie” type liners, right?

The material your spraying comes out of the top of the cup through the spray gun so you don’t have to worry about having a hole in the liner,you use the liner to keep from having to clean the cup out.

Do you have an HVLP style of spray gun, where the holding cup is above the spray gun nozzle? If so I do not think the cup liner will work for you. If you poke a hole in the bag your finish will just leak into the spray gun’s cup.

Why do you want to clear coat a table saw? Just paint it with machinery grey and start sawing. If you want something harder get a quart of paint at an automotive paint shop.

Omar, I suggest you re think your approach to the Unisaw. Scratch resistant usually means a lightly softer finish, which is why most floor finishes have a urethane resin and plenty of oil cooked into them. Secondly, if you use the proper paint, it will be as hard as any top coat you apply to it…so your finish approach should be to find the proper paint and leave it as is (IMHO). I think in the above exchange, Jim called it….a gravity gun won’t work with those liners.

Thank you for all the replys. I’m just getting back to this today. I purchased some latex paint which was my first mistake. I think I’m gonna sand it down today and pick up some automotive paint. Thanks guys
