Not sure exactly how to handle this but today I was probing around the seams as I was getting ready to start sanding the gel coat...and found some areas where the outside of the body form were stiff and brittle but as I probed underneath the hard outer surface there was quite a bit of uncured gelcoat. So I am assuming that I need to remove the outer surface until I stop finding uncured gel coat and then rebuild that area with body filler? Is this the correct way to proceed? Appreciate any help!
