You seee that there is a lot of those rivits to be fixed on the damaged portion of the hull as each cross section holds with at least 8 of them! Lots of work but it really looks nice. Notice that I also fixed some bits of plastic cross section, so that it looks like the torch of the ship cutter went through it (only way to go away with the weird way in which the ship has been cut!)

Now I cut out the rivits from what's left of the photoetch fret -it's quite convenient to work this way as it would have been hell to use some granbdt line type rivits to do the work..

At least 2 coats of mastic to do the joints as the stuff really retracts a lot.
of course, sandng between each coat

So now I had my second fret ready. It's in a way better state than the first one. i finally understood what i did "wrong" with the first one so that it looked so err, rusty.
It's quite important that i am able to control these kind of effects if i want to succeed the whole thing..

Anyway, I attach it using superglue and some clamps so that i don't get in trouble with the round shape

here was the fret for the lower part of the hull as done in a drawing software.
The point is that their must be the less possible white left, as those empty places will get bitten by the acid.
->the less copper in the acid, the more your acid bath will sty efficient.
Notice the rivits plates.
