Bye bye paint.

If I get a bike with an aluminum frame and HATE the color can I power sand/grind or sand blast all of the paint off and leave it be, just bare burshed aluminum? Must I spay clear-coat or re paint, if so any guides or sujustions, I'm a DIY kinda guy.

Gelled stripper works good. I would not blast Alu. If you use stripper the metal will look just like it did before paint.

Alu does not require c-coat, but would stop scratches to some degree.

I used Lepage Poly SuperStrippa. 3 coats 1\2 hour between.

What color is it that it's so hideous that you have to get rid of it?

You sure? Admittedly I've never tried doing what the poster suggested, but I've worked with a number of other aluminum products. If they weren't anodized, clear coated, ball burnished or something similar, they developed an oxide film over the surface that not only looked dull but also made your hands black whenever you touched them.

Let me be the first to say that I do not think you should spay your frameset. You must first be absolutely sure before moving forward with this... I've seen far too many framesets damaged for life by removing the wrong genitalia.

Yea, you're definitely gonna want to put some kind of clear coat on there because oxidized aluminum is not pretty.

Yeah. Ever seen that black crap that builds up on your water bottles if you use aluminum cages? It'd be like that EVERYWHERE!

You're not talking about celeste, are you? Calling celeste ugly might cause a few forum members to call curses from the Bianchi Gods upon you.

No I ride Chromoly, hate Alu. My only real advice is using the stripper over other metheods to not scratch the metal..(sand, polish..bla) If you use the strip, a quick buff and coat. I've done 2 frames this year and it was sure easier than sanding.

How do they treat Alu components to stop the oxidation? alloying elements?

ALSO> What would be the better coating? I used Diamond C Varathaine. I was watching a car show and they were treating raw steel with an epoxy?

(Sorry I relize i'm off into different metal type.)

Edit:
Sorry RetroGrouch...you answered the first question already..I should pay more attention.
