Stainless Steel "rust" marks on paint
Peter Hendra wrote:
Hi, I know that this possibly has a simple answer that everyone but me knows, but is there any way I can prevent the unslightly brown "rust" marks on my white hull paint from a welded fabricated stainless steel fitting that is bolted on with stainless bolts? I am about to spray on the white topcoat over the primer during a hull repaint job and I'd like it to stay looking good. I suspect that the drop ladder on the stern is not made entirely of 316. It has been 15 years since I fitted it, so that I can't recall whether the bolt is 316, 304 or (unlikely) something else. There are no 316 markings on the bolt heads. We use oxalic acid powder mixed with water to get rid of it but it always comes back. I am beginning to quote Lady MacBeth when I rub it away ("out foul spot") and it's embarrassing when passersby overhear. I know that there are several (expensive) "special" products to clean it with but I would appreciate some knight on a white charger offering me a permanent fix. It doesn't matter if he's young or old, handsome or otherwise - I'm not playing Sleeping Beauty - so long as he or she has the answer. I wonder whether it would be possible to electrically isolate it with say, a teflon washer? cheers Peter (who actually sails places and doesn't pretend to) where is the rust comming from the weld or the mounting point or the bolts them selfs Shaun |
