Title: Developping a new Bagheera Bonnet pannel IV

So, when all the panel has been glued with the new dimension, I can unfix it from the outside skin I used.
Turn it upside down and start filling the gap.
For this I use fiber reinforced filler.

Actually, even if this filler is mandatory, it will generate some issues.
First it is very hard to grind down.
Also, this will generate irritating fiber powder.
In order to produce the mold, I'm using various types of fibers.

1) Very light vowen fiber. Not a lot of strenght but will adapt itself without difficulty to any type of curves.
This is a must as first coat (after the gel coat)
Price : About 8 euro for a square meter
2) Matt. Very good, powder impregnated so that it will drink the resin. Not as flexible as the first tissue but will still follow the curves reasonably well. 300 (exist aslo in 450 or higher)
Price : About 2 euro per square meter.
Use a couple of coats
3) Old Matt. Don't remember where it came from. Doesn't follow the curves. Good to arm yourself. Don't use this !
4) Very dense vowen tissue. Difficult to impregnate but will provide a lot of strenght
Now the mold is about done.

But I got too much allergia from this powder and I'll stop for a week.

Great work, Spyros. Hope you will recover from the dust-exposure! :)
