It all depends on what you are going to do with the interior, and what it is like now... If you have a newer AS then you might see what the factory recommends. If you have vintage, like we have... we scrubbed down the interior walls with 409 and a green scrubbie, rinsed and hubby painted with new zolotone. Love it! zolotone is nearly indestructible!
