Proseal round 2 - 6 hours

One of the potential issues when back riveting the prosealed rivets is to be left with a protruding head in instances where the proseal is too thick around the rivet head. In my efforts to guard against this, i have chose to set the rivet head into the hole with a dolop of proseal, but after it is set, I give a bit of a swirl motion around the rivet head with my finger to ensure that there is no 'doughnut' of sealant around the rivet. The idea is that it is nice and flush when I put the back rivet tape (electrical tape) over the rivets.



I have used 3M green tape to protect the areas that I want to keep clean. It is important to do this work before you mix up the proseal. Ask me how I know.

I applied proseal to the skin to ensure all aluminum is covered. Then I back butter the stiffners. Ready to back rivet. Once done, then I made sure that i had a good fillet seal all the way round. Then I removed the tape and gave the skin a good cleaning with polywipes. I chose to keep the skin clean after riveting with a good wipe after, but I avoided cleaning up around the rivets themselves in efforts to make sure I had a good seal. I put proseal into a large veterinary feeding syringe and gave each rivet head a dolop of sealant.



Two tank skins...done. Ready for more!
