thats not paint....
I think if your alternator was bad you would see your lights start to flicker ect. Stalling out can be a bunch of problems but you still might want to do Rated R1's test, never hurts to check.

NTB will check the whole system while its running with a computer diagnosic. 10 bucks and it tests Battery, Alternator, Voltage regulator, starter etc. Gives you a print out and will show if your alternator has any burned out diodes. Most have 3 diodes and if 1 or 2 die the alternator will work but will put out much less AMPerage. Have it checked on a computer diagnostic. 10 bucks is cheaper than just replaceing 200 dollar alternator or a 70 dollar battery.

The altenator warning lamp should illuminate when it goes bad. Misfiring can happen.
Isn't there a way to measure output with a multimeter?
Make sure your battery terminals are clean too.
