    Where we are stuck is the quality of product comes secondary to application , without a good key and an airtight finish nothing will last .

    Couplertec.....there you go 2 more Quacks. If only part of the car gets wet it cannot work....so doesn't.

    I assume when a new ship is built the steel hull is cleaned and painted to the best ability but I think they still rust.

    The salt on our roads is a big problem. Even when dry on the car the salt reabsorbs water when the humidity in the air increases so the car will rust away even sitting in the garage.

    When I used to cut metal back to very lightly rusted areas to gas weld new steel on I could smell chlorine so I think salt must have still been present. I don't know what happened to the sodium lol.

    Either way, Couplertec either works or is an elaborate hoax. Until I have personal experience, I'll keep an open mind. After all there's going to be a lot of opposition to it from paint and protection manufacturers if it actually does work.

    Another was viewed for me yesterday. Worse than the last one.

    Search now expanded to included non-land cruisers, very reluctantly. Mrs JB has decided on what she wants (E class convertible, with me having a 4x4 which we/she uses when seats needed), and there's a 0% deal on at Merc main dealers till tomorrow. So will need a 5/7 seater to replace the galaxy asasasasasap. Not driven the E class yet and its damned snowing.

    Damn.

    How long would you be thinking of keeping the 120 for?

    3 years.
    Needs to be "nice" enough to do 3/4 weeks in Europe/trips up north etc.
    Pal just brought round his L322. They don't half have their problems, but they are quite lovely, and drive very nice too.

    If your only keeping it for three years and your happy with the rest of the motor/price is right/ needs no welding. id be tempted to get it then.Id spray underneath with diesel and then engine oil, repeat yearly.

    I'm not necessarily disagreeing with others, but I do side with Frank's use of oil.

    I squib oil into my chassis boxes, and when I came to remove and replace the ARB front bumper a year or so ago, the visible interior of the front chassis box (where the ARB mounts) was oily up the sides and on the soffit (underside of the top).

    IME, oil creeps and the rough nature of surface rust actually enhances the capillary action of the creeping.

    There's no way to treat the interior of closed box sections other than an acid dip or similar with a zinc dip to follow, so for regular annual maintenance (in the summer) I squib oil.

    Collie Chassis after acquainting it with an aggressive wire wheel on the angle grinder, Curerust, etch primer, matt black and smooth Hammerite. The inside was coated with engine oil applied with as syringe through all the holes in the chassis sides. Done end to end so it can be done. I used all my old aerosols up but probably would have cost about £80-90 to do.
    I did all the under floor in a similiar fashion but finished it off with Waxoyl based underseal.

    It might resist the salt a bit now, as the Collie is my winter driver till spring.

    You either sit and watch telly at night or get in the garage and get things done. This is why I don't have a TV at all. It took me about 3 weeks to baseline the Collie and get it towards where I want it.
