Sandblasting will remove this Preschool Attempt to paint the pipes. It may also show areas of potential leakage or pockmarking! Hopefully this is not an issue with your pipes. If it is you better go get a tubing bender and get to work! I prefer to start with an 8 foot section of pipe, fill it with Super Dry Sand, weld the ends closed and get to bending. The sand prohibits the pipe from necking down at the bend and you can get some hella tight radius!
