    Hello everyone, i am fairly new into the world of metal prep. work and polishing and have a few questions.

    First of all, i find that sanding down metal is very time consuming, be it by hand, drill & bits or an angle grinder. If the surface is flate, there are no problems, but curves are an issue.

    For example, i spent 2 days sanding down my intake manifold with an 80 grid paper on an angle grinder. The casting marks are gone, but i would still need to use a lot of elbow grease when sanding with 220 and finally 320 grit to remove the swirl marks and get a nice finish before buffing & polishing.

    My question is, wouldn’t sandblasting be quick and easy? would it remove scratches and i would need to use a 320 grit paper to smooth it down before buffing and polishing?

    And fast/easier way of sanding/smoothing metal?

    Sorry for the amateur questions, but i am new 😉
