What may look like a small corrosion problem where the old nautolex covered plywood floor meets the hull and transom, could very well be just the ‘tip of the iceberg’. particularly in older alloy boats, where often the floor was simply screwed to a sub-frame, this problem all too frequently occurs.. 2004. a. corrosion is a pretty normal phenomena that doesn't necessarily require electrolysis (galvanic corrosion). i'd paint the transom with either a metal-free aluminum priming paint or, if you can buy it, an organo tin paint, tbt (this is truly biohostile stuff, and is allowed only on aluminum if at all).. Are commonly used in boat building, such as aluminum and stainless steel, encounter their own corrosion related problems. for the wooden boat owner and builder there is a special kind of corrosion that occurs around metal fasteners, most often screws, embedded in wood, called by some woodburning..
I've restored a lot of aluminum boats, and found that pitting/corrosion is common, especially adjacent to fabric triailer bunks and guides which hold moisture next to the hull. i remove the corrosion with a wire brush and/or soda blasting and use an epoxy metal filler like jb weld for small areas.. So, i put my boat up for sale, and have had an offer of a trade-in from a dealer toward the purchase of a new boat. however, while thoroughly cleaning it last week, i noticed some corrosion around the windows and fasteners.. Aluminum boat corrosion treatment is essential. all boats require maintenance, but many aluminum boat issues can be avoided with proactive care..
