I bought a cheap 4" wet saw at Lowes because I only had about 30 sq ft to do. I'm taking that saw back today because it wouldn't cut thru the plastic. I don't know if it was the blade or what. I then went and got a 7" portable wet saw and got spare, higher quality blade.
The 7" is working just fine with the blade it came with so I'll take the spare blade back.
