    As posted in the past I am doing an R-Model replica. I was wondering what your thoughts are regarding keeping the bottom red oxide or applying some sort of undercoating. The car will live in LA where the weather is typically ideal.

    Would not even consider undercoating the bottom. Harder to keep clean, doesn't look "factory", just one more thing to do, and no real reason to do it IMHO.

    Also "suggests" your covering something (repairs, ugly welds....) up/over

    Just put red oxide!
    Remember undercoating is too much weight! :thumbsup:
    I love the work you do on the car!! Fantastic.

    Keep it up.
    Bye Jerry

    Personally, I don't care for the look of undercoating. I think it looks messy. I would personally do the red oxide.

    Just my 2 cents.

    Undercoating had a fatal flaw - it would shrink and lose adhesion with age. That allowed moisture (and here in the Northeast corridor where they use salt in the winter) brine to accumulate next to the sheetmetal and actually accelerate the deterioration process - since it was "protected" from drying out.

    We had a local Trailer manufacturer change over to paint in the late 60's when the boxes on their New York State runs were found to have their rear wheel pickup points all rusting through - unseen because of the undercoating.
