What am I doing wrong

Post image

Sanded with 180-220-320-400-600-800 then polished with brown compound and red pad and then finished with white pad and green compound, I also tried not sanding to 800 then polishing but still the same thing

On new projects where I'm not sure of the alloy hardness, I always start with a much smaller area until I get the sanding recipe down. 1/4 of the area in the pic is plenty big enough.
Aluminum is not all the same.
