    Bought a new roadster, steel body and fibreglass fenders. First time driving it down gravel road(very slowly) to get home we got two spider cracks on rear fender. Does anyone know of a protective skin that we could install on underside of fenders so this does not happen again. We were told there once was a rubber product that "the old car centre" in BC had but they told us its not manufactured any longer. Other people must have this problem. We want to drive this car and not have a "trailer queen"!! It does have an undercoating but I guess it wasn't thick enough or something?
    What would be the most rubbery of all the undercoatings?
    Thanks for any suggestions

    I would thing a liberal coating of bed liner material would work well.

    First off its just not glass fenders that get star cracks. Steel fenders star crack as well. My 35 Chevy with steel rear fenders has several star cracks. Several years ago at the Shades of the Past there was a vendor selling a product called "Star Blocker" which was sheets of rubber you glued on the underside of fenders with weather stripping adhesive. I installed it on a 32 Ford with glass fenders and never got any star cracks. I've also heard of using bed liner as well.

    Spray on bed liner is really the only acceptable method and also the most effective.

    A good thick layer properly applied and the problem is no more. :)

    Bed liner, but make sure you scuff the glass first, if any release agent or glass residue is there, the stuff will fall off when the car is in the sun................ask me how I know!

    FYI you can buy a bed liner gun for less than 100 bucks and it isnt hard to do. Just make sure you have everything masked off well and covered with plastic as it can get messy.
