    Hi all.....have any of you had your shell dipped? If so, what did you do about the area between the upper and lower windshield cowling? I have both of mine removed right now to replace sheet metal due to corrosion damage (65 dart), but am wondering should I leave my outer off until it gets dipped and then treat and paint that area before I put the outer back on? I seriously wonder how Graveyard Carz does it....they couldn't possibly leave that area bare raw metal do they? Anyway....just wondering how any of you have done it....Thanks in advance....

    Some dip them in epoxy primer after metal replacement and before mud work.

    If you chemically dip the shell to have it stripped you need to dip it in epoxy primer too. If you don’t there will ALWAYS be areas that are left bare. If you have it chemically dipped and then paint it with a spray gun you’ll never get everything that was stripped, and the concealed spaces will rust even faster because the chemical dip removes the factory metal treatments as well.

    So places that do the dipping have epoxy vats as well?

    They typically do both, yes. Chemically dipping a car without doing the same with a sealer or primer is a sure fire way to flash rust it. Or worse.

      you have to find a dipper that caters to the car resto crowd as there are dippers that do all sorts of work for various metal manufacturing industries. the cradle that holds the car needs to tip and roll to release trapped air as it goes into the tank, like the top of your car where your head liner is. the restoration shop I know that does have their projects dipped to strip the cars follows with metal replacement of rusted out and damaged areas and general straightening of the car. it is then sent back out to be dipped in epoxy primer. this seals the metal which build primer does not. how they treat it for flash rust after stripping and before epoxy priming I do not know. when the car has returned after epoxy priming, it is skimmed with filler/shot with build up primer and the sanding begins to get it flat. after it is totally flat and straight, the primer is sealed and painting with color begins.

      I haven't seen epoxy primer dip but I have seen E-cote like the coating on new sheetmetal parts.

        actually I do know how they keep it from flash rusting after dipping, they spray or dip it in rust preventative. one guy in Florida that does it coats in a nitrate solution and says it keeps it from rusting for 30 days. you have to remember its not just a chemical dip, its an electrolysis process in a caustic solution.
