Getting these blasted rivets out of the tanks is proving to be far more difficult than I had anticipated, and I was expecting it to be difficult. I bought at USB “borescope” camera off of Amazon for $18. Its a cheap bit of junk but it serves its purpose. With this camera I was able to remove many other rivets. Next I tried sloshing water. This brought out a few more rivets, but at final count I was still short. Finally, I gave up and drilled the baffle off of the right tank. Drilling rivets was easy. Removing pro-seal was not. I destroyed the baffle in the process and had to order a new one from Van’s. I’m now 5 rivets short of having them all. I’m not going to remove the other baffle as I’m convinced I can get the remaining five with a combination of the camera, magnets, and sloshing water.
I attached the camera to one of the telescoping handles I have for an inspection mirror. Then I affixed a piece of string to the very end so that I could manipulate the angle of the camera inside the tanks. It worked very well. Lighting was a bit difficult with the high reflectivity of the aluminum.
