    Subject: Re: inspection and corrosion
    It will depend on A) Were the wings and tail alodined and primered with epoxy? B) Were grommets installed in the cloth so that water vapor could get out? C) The kind of rivets used. The early Kolbs used very thin wall tubing and used regular steel pop rivets rather than SS. D) Was the fuselage cage painted or powder coated? If the cage is white and you see rust colored stains all around it's probably powder coated. If you use AC 43.13 as a guide you'll have to sand to bare metal and restore the finish after priming. I like to use epoxy for this very reason. The picture is of the interior of a Firestar 1 wing which had no grommets and poor priming of the parts before assembly. It also used the regular steel rivets. It was from Pennsylvania and had this kind of corrosion throughout the wings and tail. Not good. Good Luck.
