Before we go on...Lets just be clear. I have found out the hard way this is NOT HOW YOU SHOULD COMPLETE THE FIREWALL. Read on and learn why.
Super long day of work with not as much progress as I would have liked. Just a very fussy process.
First order of business was to apply a thin layer of sealant as a fay seal between the aluminum and the firewall. Now...I had it in my head that this would go easily, but let me assure you it is not. The sealant is extremely thick (much thicker than proseal) and it takes a considerable amount of time to put it on the angles and get it thin with a plastic scraper. I should have stopped at this point.....I didn't
I continued on.... I began to worry about the silicone setting before I could rivet it. So I felt it wise to clamp some of the more important areas. This process becomes extremely difficult as it is vital to cleco the pieces to get it tight, but you cannot back rivet with the clecos it.
I just kept going.
And going...
It was nearly 3am I think when I finished... Some of the rivets will need to be re-done. I worry about it tomorrow.
