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
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.
ill stand corrected, i was thinking about something else while posting that, moreso to do with steel trailers.
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

You can consider Star Brite Sea Safe, It is a cleaner that has a completely biodegradable formula and doesn’t contain any type of acids, chemicals, solvents, or phosphates. However, even though it doesn’t contain any harsh acids or the like, it is still very effective. In fact, you don’t really need to do any scrubbing with this cleaner. All you need to do is apply it on the intended surface and you can just wipe off the stains.
