Lots of cleanup of the inner panels. Mostly wire wheel on a drill. Slow, tedious work but it really works well for the irregular shapes. Respirator and eye protection mandatory to avoid the orange cloud.
At this point the panel has been rough fit many times and the outer tub is now in place.
You can see the trunk floor and part of the hinge flange has also been stripped to bare while the quarter was off. Many hours climbing around in the trunk.
Everything clean and bare steel will get a heavy coat of DP90 epoxy. Surfaces like the sail panel which still have some surface rust will get POR15
