[QUOTE="DaleH, post: 435017, member: 15636"] I like brass brushes to remove corrosion, vaccum & rinse w/ fresh water. Then a straight vinegar wash ... don't dilute it! You should zinc chromate prime spots before epoxying. For any area subject to flex, I'd use the GFlex ... it goes a lot further than you think and around here the kit is only $20, so for 2 maybe 3 kits, man you'd be using a superior product IMHO. If any corrosion does goes thru the tin skin, you need to completely get rid of any "white" showing in the layers, as that is indicative of a inter-granular precipitate attack. Such an attack [u]feeds on itself[/u] like a cancer, and it must be completely cut out! I see this on saltwater boats. And like a cancerous tumor, it too would be completely excised ... Be AWARE I once started w/ BB-sized holes that had the chloride attack ... and once drilled out beyond the boundary ... those holes were now 1/2" holes or bigger. I ended up completely REPLACING my transom skins, as shown in my profile posts. [/QUOTE]
