1/26/2009 … Section 18-5 Step 4. Started the completion of using the “Pro-Seal” with the final riveting of the Tank Stiffners to the Tank Skin T-1001 L. After using masking tape to shield the area and then removing the “alodine” (shinny ) finish with the die-grinder and the proper sander attachment I used MEK or Methanol Ethyl Ketene and a shop towel to properly clean the surfaces including the rivets before applying the “Pro-Seal” substance. Then by using the “back-plate” riveting technique I was able to obtain a very nice finish on the factory head of the AN426-3-3.5 rivet. Time about 3 hours for the Left tank only because I was working slow and carefully because of the “Pro-Seal” is very untidy material.
