    Has anyone tried thermal sprayed zinc process on ungalvanized bodies?

    Has anyone tried the thermal sprayed zinc process to provide anti-corrosion? A friend of mine is building a (non-Porsche) rally car and has had this process done to the underbody... apparently the process came from the shipbuilding industry and is highly effective.

    Here is a link to a video of the process:

    Thanks in advance for your comments...

    Yes that works, I've used it on body parts and the same process but with aluminium instead of zinc for exhaust manifolds.
    I won't ever use it again for visible surfaces it leaves a rough to horrible (depending how good the job was done) surface that will only be good for underbody areas. I used it also for undersides of Doors and it was a pain sanding it down to a semi coarse surface. Primer has to work with zinc, I remember that back then you first had to wash down with Ammominak then use a special primer followed by epoxy.
    Cheers

    Sorry for the hijack.
    May I ask why you use aluminium instead of zinc on exausts?
    Has the aluminium any advantage over zinc on manifolds?

    The guys who did the work take aluminium for Manifolds as it is better for Parts that get hot.
