I got my frame sand blasted and it looks pretty cool can I just leave it like that or it needs to hava a special type of coating?

to keep it from oxidising, it needs a coat of clear coat.

let it oxidise, the layer of oxside on the surface will act as a protective layer. but dont go cleaning it off, then you will be taking materail off, not thats its much but eventually.... if you want it to be shiny then put a clear coat on it.

How about those bikes that are brushed aluminum do they have any type of coating?

 

[kieram]

aluminum doesnt have to have a clear coat, you can leave it as it is and it will be fine

 

[SteezyWeezy]

it will oxidize, but it takes a while to weaken i think, you're probably fine

Guys, aluminum will not weaken if allowed to oxidise. The oxide layer is chemically bound to the metal itself, and isn't going anywhere. This is why cmponents must be chemicaly stripped (in an acid bath) before anodising. If left in raw form, a thin oxide layer will form over the surface, and simply stay there, preventing further oxidation/weakening. Leave it raw. It'll be fine.

purple annodize it

If it's 7005, it will probably start to look like crap, that stuff corrodes pretty bad.

My Sinister is coming from the factory raw. I was told today by Sinister 'honchos' to use mag polish 1X a month and it should all be good.
