    Stripping M70 valve cover paint

    What has been your preferred or quickest way of removing paint off M70 valve cover?

    I am trying to avoid using any sand or bead blasting

    Dip it in a strip tank for 10 seconds.
    Rinse with pressure washer.
    Viola! Bare metal.

    Then Cerakote it. Much more robust than powder or paint.

    Thanks! Is strip tank the same as a hot tank?

    No. Go to a powder coating / blasting place and ask them if they have a caustic dip tank.
