Just a one time job but I used an electric pressure washer and a surface cleaner to get the siding prepped. Took all the chalk off without being too harsh and it was neater and quicker than the regular nozzle. After that I painted with SW SuperPaint and it's holding up around the 5 year mark I believe. I did not use a primer either as the SP said going onto aluminum nothing was needed.

I think I just used some pressure washer cleaner initially but the surface cleaner is a pressure washer attachment for cleaning usually sidewalks. Faster and less spray back. The electric one was super lightweight too so really easy to just go along the strips and wash them.

As for actual painting though I did not want to use a roller and clean up all of the drips etc on the edges so I purchased a paint sprayer, I think the X17. I was done with the majority in under 2 days. Used a paint shield and masking where I absolutely couldn't get the shield.
