Hello, I had this problem, I did not smell thinking the resin was fresh.
I got off completely. Fortunately I noticed in time.

Re: My cx 25
Your boat is looking great!
What is the problem in the last post?
The faring compound did not bond with the resin below?

Re: My cx 25
In the second and third picture the fiberglass looks very "clean" (not sanded). What speed hardener did you use? How soon after fiberglassing did you put the fairing compound on? It looks like from the dates on your posts it could be around 5 days. With that much time in between (anything over 24hrs) I've been told to clean and sand the fiberglass to make sure the next layer of anything will stick.
I'm curious to hear what everyone else says. ...

Ugh, that looks like a lot of work and material down the drain. Improper ratios or underlying resin/glass needed at least scuffing. My .02
You are doing nice work there, the hull is coming together beautifully.

Re: My cx 25
There could of been some amine blush that caused the delamination. It does look like from the pictures that the fiberglass surface was very shiny indicating it had not been sanded. Sorry you had to deal with this. The adhesion appears so poor, that perhaps the cleanup won't be too bad. Otherwise your build has been a great one to follow. Wish you all the best in the continuation of your build.
Re: My cx 25
Actually I had not had a cart. And after sanding, and it's ok.
Re: My cx 25
Regarding cleanup, I would suggest using a blower nozzle on an air compressor if you have one. Follow it around with a plastic spreader to help guide the airflow, it should allow you to just "peel" it off with the compressed air, depending on the amount of gap. The filler used looks like straight silica and epoxy? That's the only explanation I can think of for why it looks so brittle.
Re: My cx 25
Thanks for the advice, I used epoxy glass microspheres.
I solved now I have repainted the stucco and everything adheres very well.

Glad to see you solved your problem. Please keep posting pics of your build. Always interesting to see these cx/cs boats come together.
