We used this OATEY PVC AND CPVC PURPOSE PRIMER (which comes in an 8 ounce size, with a built-in brush to use as an applicator) to help remove some dirt and oil from some PVC piping and prepare the pipes for applying the PVC glue to the pipes which we were installing for both a pump we installed and piping for our orchid house; this product worked well and was easy to apply
The product worked well and the purple color of the solution helped to identify where we needed to apply the solvent, which is very helpful
Pros: Easy to Install, Good Instructions, Reliable, built-in brush, colored liquid, Easy to Use, works well, works fast
