The fuel tank attach bracket is made of 6061 angle. I have finished my tanks without leaks and moved on. As I was starting another section in the plans, I just happened to glance at a section of the fuel tank instructions, and now I'm wondering if I have to jump back to redoing something on the tanks. I did not prime the T-905 attach angle before I riveted it onto the inboard rib because I figured I'd hit it with primer when I paint the entire tank down the road. When I was building the tanks I was in the "don't prime anything" mindset, and I just didn't think about the fact that the mating surface between the attach bracket and the rib should get primer.
So the question is, do I just prime the rest of the bracket down the road when I shoot paint, or, is this critical and I need to rip things apart to drill out the attach bracket to prime that mating surface? I can't remember if I put proseal on that surface or not (I think I did on one, but not the second tank, because I realized that as long as I sealed the inside of the tank, the bracket didn't need it). I'm really dreading the thought of pulling off the access panel and drilling out the bracket just to cover a few square inches with primer, but now is the time if it truly needs to be done!
