Peeling window paint
So I got a wild hair and started peeling some of my flaking window paint off. Some of it flakes right off with a razor blade very easily, but much of it is surprisingly still stuck on pretty good.
I'm wondering if I should stop flaking it off where it's still stuck good and try to "blend" the new paint in somehow.
Would it hurt the underlying aluminum if I got my little finishing sander after some of this stuck on paint? I did a little hand sanding and it scratches up the aluminum pretty easily so I stopped.

Having tried this job in the past, I suggest a few things: (1) I would complete the removal because chances are the old paint will continue to flake under the new paint (2) After removing with your sander, you need to use really fine grit (800+) wet and dry paper wetted to finish the preparation (3) paint with zinc chromate x2 coats (4) ready to apply 2x coats of your preferred finish paint. I use spray cans but it is difficult to control over-spray, especially if there is any wind at all. I think if I ever tried this job again, I would brush on and probably use a water-based aluminum paint. Unfortunately, even with all this prep, repainted aluminum does not stand up as well the original finish. Good luck!!

Thanks. I will start sanding.
Instead of painting this aluminum, what do you think of just polishing it up a bit and leaving it like that?

If you polish it out, I'd coat it with a clear ceramic coating.

Definitely sand to bare metal. Make sure after you complete your prep that you use a DTM(direct to metal) primer and compatible paint. Brands are personal choices I avoid but making sure it is DTM rated is vital.

Peeling window paint
After sanding a bit with 120 grit paper on a little black and decker sander. This paint is surprising thick. Takes a long time to get it off.
Could I go with a more aggressive paper?
I actually don't think the bare aluminum would look bad with a little polish. But I'm probably just being lazy.

Greetings,
Mr. 01. I think more aggressive paper might introduce deep scratches that will be hard to get rid of. Patience grasshopper...

Gel coat does not like to be sanded, just FYI.

I would try a heat gun.
Or Citri-strip.

What if the Citri strip got on the gel coat?
I do feel like I'm sanding away quite a bit of window frame here.

As sdowney suggested use stripper. Tape off the fiberglass then tape plastic to the tape to catch the drips. Rinse with water to neutralize whenever you stop.
You can get scotchbrite type polishing pads that will go on your grinder or polisher. Much quicker than various grades of sandpaper.

My guess is those windows are powder coated. That's why is was do hard to sand it off. And you saw no primer under it.
If you are going to polish it out, there are no short cuts.
It's a multi step process.

Peeling window paint
I actually used the Criti-strip stuff on the top section and that came out better. Plus it's more my style--apply stripper, drink beer, check stripper, drink more beers, etc.
I don't think I need a super high gloss finish on them. I don't mind the flatter look whatever that's called-- brush finish? Just need to get all the oxidation and scratches off and make the frame look even.
I realize the aluminum window looks a little silly next to my painted door but I really don't care. It's a manly window. Not a fussy, glossy, high maintenance pretty-boy window.
Think the paint dust got to me...
