Sometimes you need something new, or me this feeling comes in the time of the year when the days get shorter...
So, while beeing in love with my Caad9, I have started stripping a Caad10 frame.
This bike is my inspiration,

The frame (size 54) was 1250 gr without bottlecage bolts, derailleur hanger, seatpostcalmp etc.
Hope it will be around 1100gr when finished.
At the moment I just put on some paint removal stuff, see how it will turns out.

I always wanted to do a polished aluminium bike. Just seems silly to paint aluminum somehow. GOOD LUCK!

Wow I have the same frame. Silently inside a part of me is crying.

White paint is heavy though.

I was thinking of getting my Caad10 anodized purple and having the hollowgram arms anodized green. I have the 2012 brushed aluminum frame and I am kind of bored of it.

I hope you weren't stripping the frame just to get 150 grams off.
you are in for a disappointment. It will be in the order of 60-80 grams.
Now if it was for the polished finish, then you'll have a double bonus.
But be prepared, it's gonna take some work or money to get it a nice
as the one in the pic. Hope it comes out well.
Second, white paint is not any heavier than other colours. What you're
getting confused with is that on a carbon frame which is black, it takes
more coats to get the coverage to look white or a bright yellow not to
have a green tinge to it.
As for the anodizing. A frame can be anodized if: any steel inserts on the
frame such as water bottle bosses are drilled out and new ones installed after
anodizing. And.. if you understand that anodizing colours are affected by
the particular alloy being anodized. So the weld zones, which are a different alloy
than the tubes won't have exactly the same shade of purple as the tubes.
Black won't be as bad as some other colours. A good anodized will be able to tell
which colours will come out with the least problems.

Here is a frame that was stripped, polished, and then anodized, which shows the difference in colour on the welds that wally318 is referring to. I wouldn't actually do the hollowgram arms though.

My first reason to strip the paint is because I don´t like the liquigas colors.
On the other hand I am very impressed by the polished r600

Little weight savings comes second, but would be nice.

After stripping the downtube I have saved 10 gram...

Here is how the fork and frame look by now

This is what happens with anodizing:

Welds look shitty, but overall very nice.

Meh....retro-look the welds by doing a hand lug lining (old school....and yeah, I know it doesn't have lugs) if you really hate them. I'd be more worried about changes in composition of the thin section tubes. Caustic processes (both stripper and anodising) remove zinc from the alloy quicker than it removes Al doesn't it?? (or are the changes so small as to make no difference?)
Updated: Racing again! Thought this was unlikely! Eventually, I may even have a decent race!
Edit: 2015: darn near won the best South Island series (got second in age
-group)..woo hoo Racy Theremery is back!!

I don't think it's too bad. Sloppy untouched welds are never going to look good, even with paint. The contrast from the anodizing maybe gives it a no-nonsense look. In any case, what's this about "only" 50-80 grams???? People spend $200+ to save that much. And a quick search to this forum finds examples where it is indeed 100g+.

On a round tube frame like a C'dale that's about all you'll save on an alum. frame.
On a bladed frame like Cervelo etc a bit more because of large flat surface+ more
paint. Only alum frames that have really heavy paint are when they're powder
coated, which is much thicker than standard 2 part epoxy type paints. Also much
harder to get off. 100+ grams of paint are usually on carbon frames.
