I don't know the answer to that and I would ask a painter

Yes you can paint aluminum clad siding house. Have to make sure you get it washed down with good tsp (trisodium phosphate) and bleach solution, to take away the chalky residue on dried aluminum. use a good exterior bonding primer which can be tinted. Then a few coats of good exterior paint does the trick. VALSPAR or Sherwin WILLIAMS for a good exterior bonding primer and paint. Been painting since I could walk. hope that helps!!!
