    Question What to spray raw aluminium with to stop oxidation

    So paint is flaking off the block in a bunch of places on my RXP, early in its life it was used in salt water.

    I cleaned most of the oxidation off and all seemed all right till I looked at it again few days later. I see small white bubbles everywhere, as if mold started to grow on the exposed aluminium

    What can I coat it with after a wash to stop this? This is now a fresh water ski.

    Spray it down with fluid film or get this from home depot http://www.homedepot.com/p/Blaster-1...-CSP/202536139 this stuff goes on liquidy but dries to a vaseline like viscosity, which will not easily come off unless you use a degreaser.

    I'll soak everything down with silicone spray.

    You can't stop oxidation on aluminum unless you're a metallurgist in a vacuum sealed lab. I think. Aluminum never corrodes usually because it oxidizes immediately. Scratch a piece and oxidation will be right behind your scratch tool.

    Clean it best you can and seal the crap out of it.

    OK, it sure looks ugly when someone else looks at your engine bay

    Will try fluid film as that's what I can find locally.

    I beg to differ.

    I understand the oxidation part, and you are right; but, this will certainly help the aluminum stay nice and shiny...

    Is it something about the type of aluminium used in engine components? Aluminium docks stay nice and clean, my engine starts growing "mold" in a day

    aluminum is aluminum - till its alloyed.

    sharkhide will keep it shiny; alloyed or not.

    It's the difference between cast and extruded aluminum. Cast is porous. What you can do is remove the seat after riding,allow to dry out and when you have the seat on during storage is use something like DampRid,I believe that's the name.
