    What should be done to get the most out of older frames, both Anderson and PVP? should they be stripped and heat treated? What’s the best recoating product, is powered coating OK other then it tends to hide hair line cracks should they occur.

    Hi Gerry

    We always powder coat. OK it can hide very small cracks, but very small cracks don’t stay very small for long ;-)

    I think a shot blasted bare frame looks great, especially a fully brazed one. Just keep it clean and rust free (saves weight too!!

     

    Best Regards

    Gerry, I wouldn’t put any extra heat in the frame, it is what it is.  If the frame is clapped out, then it’s time for a new one, you can’t turn back the clock.

    Part of the process of refinishing the frame is the inspection portion.  After it’s sandblasted and stripped, that’s when you go over the frame and look for any cracks or broken welds/braze joints.  Especially look over and around the engine mounting tabs.

    so no real way to unstress the frame then when they get old?

    You guys are sandblasting frames? I was under the impression that is not a good idea due to ever so slightly changing the properties of the metal from the blasting process.

    I thought we could only dip them.

    If you going to powder coat, it needs the sand blasting texture to adhere.  My new chassis get sand blasted…
