Riveting fuel tank drain flange. These rivets were squeezed with the pneumatic squeezer.
Image 1 shows it taped off to score it with a scotch bright pad. Also to control the mess if I make one. Turns out I didn't.
Image 2 shows the rivets squeezed and the mess cleanup up with M.E.K. I tried to use the Colman Fuel but it was worthless removing the Pro-Seal.
Image 3 shows the shop heads covered with Pro-Seal. I tell you, using a syringe filled with Pro-Seal is the way to go for covering these shop heads. I made sure there's a gap between the globs so water can make it to the drain.
