ill stand corrected, i was thinking about something else while posting that, moreso to do with steel trailers.4liters wrote:Aluminium oxide is really hard (it's the same stuff as rubies and sapphires) and forms a continuous layer over the aluminium. Aluminium itself is one of the most chemically reactive metals and a layer of oxide forms on it's surface as soon as it is exposed to air which seals it off and prevents further oxidation. The more you damage the oxide layer, the more you are opening up your aluminium to further corrosion.purple5ive wrote:im not sure how the Oxide is Protecting??? oxidisation is the decaying or wearing out of the alloy. how is that protecting the tinny?
saltwater will bugger the tinny up regardless, just a matter of time, which is why cleaning it is very important.
i would wash it with some sort of wash and wax maybe thats Ph neutral so that the wax is a protection to the saltwater
i used to use a mag wheel sealant on my very expensive alloy wheels when i had my pocket rocket, they worked wonders and water would bead off it for months, maybe something like that would work well on tinnies, but might rub of where it meets the trailer etc and be useless there.
hope you find something that works well, thats why ill stick to polyboats
