I would say that in areas the plex was oversqueezed to the point of only a thin amount was left, in some areas there was not enough applied. BUT.......this is only according to the info I have read about the product. I am merely a 382 owner, engineer and a dad. What do I know...The proof will be in a few years down the road if these boats have no more issues.

Thanks, Dave

As you can see from the seam photo there is a single bead of plex that was not compressed. The plunge cutter worked really slick to remove the old plex. The knife blade could be bent slightly to cut the material from under the deck. It flexed enough to take out the plex and not the fiberglass. The 1/2 round cutter was more aggressive on the hull side of the seam as shown on the video. We packed the joint full of plex and forced it up into the seam with a bondo paddle. When the joint was compressed with the screws it pushed out inside and out. I know for sure there are no voids.

So in the picture were the hull and deck was not bonded at the factory,did Formula still say it was driver error?
I believe this is also the cause of water in the cabin that has been asked about many times.There are probably hulls out there that have not separated but are not sealed.And this is were the water is coming in.

There are through bolts every 18" or so

Could you explain the 2 pictures please. The blury one on the left looks like it has a bead of something on it. Is this a before repair, or after repair?

The one on the right with the cutter and the wedge. How much of an overlap is there deck to hull?

Copied from Fossil's post its my understanding it was never compressed and was before repair.

I read that. I wanted to confirm it was PRE repair, because the way he described the repair, there should be a bead sticking out then (after repair) too.
