aircraft stripper, will remove the coating, (for maybe polishing)
but if you're painting them, DON'T SAND ANY THING OFF, if you sand down to aluminum you'll have to "etch prime" the un-sealed surface, scuff, then prime, then sand again..
the surface is already sealed.... I'm saving you many steps here that are costly and time consuming...
prepping for paint.
first wash with dish soap to remove any contaminates (grease, oil, road grime)..
only sand the ruff areas smooth, do not sand thru it.. sand ruff areas with 600-800 and scuff the rest with a red scotch brite pad.. clean with prep-solvent. then apply paint..
first coat should be light (what painters call dusting).. second coat can be heavier.. let each coat dry for 10-15min or force dry with air hose..
