I had same issue. It required a lot of stretching.

What I did was plan installing the seal so that all the stretch was taken a= long the sides of the cockpit, and then “over the top” at the ba= ck. I did this as I could imagine the seal trying to pull away from the conc= ave sections – which would have been fun with wet silicone everywhere,= and annoying if it later pulled away!

  1. Before any silicone got close to the plane, I laid the seal= roughly in position and fixed with masking tape across the front of the coc= kpit opening with no stretch in this section – making sure of course t= hat the air line connection fits nicely in the right spot.  I then mark= ed the mid point of the seal “at the back” - effectively the poi= nt that will line up top centre of the cockpit opening at the back, and tape= d into position.
  2. I then marked a point on the seal both sides that was roughly e= qual to the length of the straight side sections, and marked the same distan= ce back on the structure. This was to give me a reference for how much I was= going to stretch the seal – with aim of getting it roughly the same b= oth sides – not that it really matters that much I guess.
  3. Next step was a bit of trial and error – but I then stret= ched both sides back to the “aft corners” (just below the latche= s).
  4. Without any stretch, I taped the seal around the corners and up= about 6”. At this point of course, the seal will not be sitting on th= e joggle up over to the top, and the masking tape you put in place at step 1= has probably given way at this point – but it doesn’t matter &#= 8211; in fact it makes it easier.
  5. Once everything is secure both sides to points just above the l= atches, stretch the rest of the seal up and over the top, but aiming to get = the top back centre marks you made in step 1 above to line up.
  6. If at this point, the amount stretch seems OK, and is not subst= antially more and less than the tension you applied along the sides – = you’re good to go!  If it doesn’t feel right, go back to St= ep 2......
  7. I then made final marks every 10-12” or so all around the= seal and the structure, so that I would know pretty much exactly where to l= ay the seal once I’d applied the silicone.
  8. The rest is easy – apply silicone (not too much) as a lot= squeeze out is bad =3D messy), and progressively place and tape in position a= s required to get it all to sit in place. Once taped roughly all the way aro= und, where required I placed additional tape over the seal to make sure it w= as really pressed into the corner of the joggle.
  9. When it was all set, removed all tape and marks.
  10. I had then intended to go all the way around and squeeze some m= ore silicone into the top gap.... But  after a year’s flying, sti= ll haven’t got onto it!!
