I let the 2nd layer dry over night. I suppose it cures, it doesn't dry. Whatever. I like it hard for sanding.
I pulled the peel ply off. This time I found a few spots vacant of fiberglass. I sanded about an hour to get it smooth and to remove fiberglass that got on aluminum where it should't have.
I have not yet layed a thick layer of fiberglass over the fabric per the instructions.
You can see that my sanding took it right down to the fabric. I don't want to sand so much that I break the fabric. So time for a layer of fiberglass.
