Okay so I've committed (for better or worse) to liberating myself from the semi-annual ablative painting and am going for a copper epoxy bottom.
To have the copper epoxy adhere properly, my understanding is that I have to remove all paint down to the original gelcoat.
Upon starting in upon this onerous process, this is what I've found:
From the outside moving in there are two layers of what is definitely ablative (dark and darker blue), followed by green, then light blue, and then white.
Here's where things get a little confusing.
The white seems hard like gel coat. Beneath the white is the dark grey (primer?) and then another layer of white gelcoat that appears to be coplanar with the gelcoat above the waterline. Where to stop sanding?
