Hello Ricardo!
As you describe the problem it sounds like this hull
has been "repaired" and coated before or that vinyl
ester has been used in construction for the layers
inside the gelcoat. Please e-mail me some more info
about the boat: Is it a known brand, where is it built
and so on.
Regards B. Blomberg

: If the process is still not well known, and lots are still
: to reveal, you can imagine the amount of missinformation,
: missunderstanding it has in a country like Brazil. Your
: approach is really ingenious and I'm decided to fix my
: beloved 40' boat using your inputs. This is a 10 years old
: hull wich old owner reveal careless. I just started a repowering
: process and I was surprised with blisters on the wet hull.
: Although the total are around 200 in the hull, blisters are
: big ones. Without sanding, they look like 80mm diameter,
: some are well visible, some are flat. After sanding and
: removing the delaminated fiber, they are 150 - 200mm diameter.
: The deep seems shalow, acid appears mostly on second/third
: layer, but some demanded me to sand 1/3 of the hull thickness,
: until I found a clear and dry fiber.
: I'd like to have a survey on the extent of damage, based on
: your experience. Using meeters, labs, etc... is a dream much
: far from our local reality.
: At same time, I'd like also to discuss your franchising model
: where I would promote among some boatyards. Pls. send me e-mail
: with informations about training, tools, method, cost, etc ...
: But don't forget to answer me about my boat's blisters, I need
: your inputs to proceed by myself since there are almost none
: knowledge on osmosis problems here.
