Oh, I didn't do that. How thick do I want to make it? How much/many
microspheres are needed to do a square foot?

You don't actually count them, they are ~20 microns in diameter. What
you do is purchase a bag of them from aircraft spruce (cheap). Make your
epoxy mixture, then start pouring in microspheres until you have a
slurry resembling thinnish peanut butter. Note, the color is a near match.


Yea, that's what I thought. I was just trying to figure out how much I
should order.



Don't forget, laying glass & spreading epoxy while fighting gravity is
messy business. If you can work it. Always try to figure out how to get
your work surface mostly horizontal.


I wondered about that. I've got a fork lift. Maybe I should weld some tow
hooks all around this thing so I can spin it.


As a matter of fat, that's what we do with our aircraft. Or, you can
make your layups on plastic bags on the floor, then apply them like they
were sticky wall paper. After the layup has been applied, peel off the
plastic bag.
