    I have an '87 BMW 325is. It was my dad's car. He passed away in 2000. Last year the washer reservoir started leaking. I finally looked at it and it is cracked on the bottom where a plastic bracket is welded on. What is the best way to seal something like that? Since it will always have exposure to fluid I don't think regular gasket sealers or silicones will work. Epoxies?

    I would look for a 2 part epoxy. Since the washer fluid isn't under pressure, a silicone rtv might work.

    If it's made of polyethylene, then it's best to find an adhesive or sealer that is specified to work with it. Many adhesive or sealers do not stick to polyethylene very well, even two part epoxies.

    It's too old to have recycling info on it, but yeah I think it looks like polyethylene. I will do some research.
