I realize that these pictures aren't the greatest- but would you guys please let me know what you think of the condition of this gelcoat?
There are discolorations everywhere-dark blemishes, and I'm not sure what they are.
I have a hunch that they are old blisters which have shriveled up- and this is what is left. I searched high and low to find out what dried blisters look like, but couldn't find anything like this. My other thought is that the old barrier coat was applied to a hull which was not allowed to dry-and this is the result of moisture being trapped between the gelcoat and the epoxy.
This was found beneath many layers of antifouling, a poorly applied barrier coat-which was actually applied over one layer of ablative paint, and a mystery pink/purple layer. There are absolutely no places where it looks as if blisters were ground out and filled with epoxy- so this leads me to believe that this may have been an attempt at a pre-emptive barrier coat, albeit a very poorly executed one.
I'd very much appreciate hearing what you all think. If you are so inclined, please click on the picture to zoom in. I think that they show the situation pretty clearly.
Thank you!
PS I feel that it is important to note that these discolorations do not extent into the laminate at all, I don't think. There are a few spots in the photos where it is apparent that I sanded through the gelcoat, and the fiberglass is exposed. In these places, it looks to me as if the chopped strand mat is in good condition, and shows no sign of un-saturated fibers or anything of that nature.
