It looks good. Your hard work sure pays off.
A tip for future projects where you want to create a lightweight, easily sandable
/shapeable epoxy contour. Go on Amazon and buy a small bottle of micro balloons. They’re microscopic glass spheres that are mixed with epoxy to make a strong but lightweight , gap filling and easy to contour mixture. It’s used to create lightweight contours and fillets etc., Think of the smooth aerodynamic contours where the wing meets the fuselage. It cuts the weight of epoxy drastically. I would think you could use small amount with epoxy putty as well. It’s so light that a pint bottle feels empty.
