Hello all,

I hope someone could help me with my "little" problem(sorry for the errors, english is not my mother language).

I just finished my mould that I made following the videos on the easy composit home page using the uni mould kit products. And I don't think I missed a step or did something wrong, but on one spot I got something strange. Something went wrong and I don't know what or why. It's like there's been some chimical reaction that gave this white layer so that the gel coat couldn't attach as it should.

I join some pictures to show you.
What should I do? Can I polish this spot then apply a thin layer of gel coat and repolish or is this a bad idea? I just hope I don't have to start all over.

Thanks in advance

From the pictures it looks like something on the surface of your plug may have reacted with the gelcoat. What is your plug made from and what release agent did you use? Is the plug surface now damaged? Was it difficult to demould?

When the exotherm kicks in the temperatures get well over 60 degrees C more than enough to soften paints and even some plastics causing major problems.

Looks like a problem called Alligatoring,
Look for it on google Smile

Might be a problem with mixing ratios, a to thin coat of gelcoat or problems with the releaseagent (at least that was the cause of the problem when I had it once)
