Aluminium alloy corrosion on frames? Marin B17 AXC

[reanimation]

Hiya, I got this off a mate a while ago. I quite fancied rebuilding it but gone off it now. It's an 'aggressive XC' frame, he used it for commuting and general trails, looks like a cable guide was glued back on and the condition of the metal doesn't look great.
What do you think?
Sell/build/donate or scrap it!?

Thats pretty corroded. Strip and inspection for cracking maybe.

Good advice. Thanks. I suppose that's the only way to know for sure. I've backed away from Ali Alloy. My arguably bombproof Dr Jekyll wasn't​ as much fun as I'd hoped and my Revolution Commuter was loyal cheap but bone shaking harsh. This could be the only alloy frame I have in stock now sort from the boss's Merlin. Be nice to have 1 in the stable. Or get rid!?

Re:

I don't think that's worth putting much time/effort into tbh.
use it as it is for a commuter bike.
you'll never get back any time/money you put into getting it looking respectable.

but then that's true of many retro bikes!

That's true even a powder coat idea for a cheap retro frame seems reckless!
It's locked in a cellar at the moment was going to dehoarding it...
