A mixture of epoxy and micro balloons in a plastic bag, squeezed out in strings to make ridges.
The distance between ridges are 10- 15 cm and overlap over keel.
Various home made sanding blocks for sanding.
- 90 cm long board with handles - used for convex and flat surfaces .
- Paper tubes, short and long - used for concave surfaces
To attach the sanding paper, I use a spray glue to spray on the surface then attach the sanding paper.
Sanding the ridges to get a even hull shape
Finished.
Some ridges are sanded down completely to the hull surface, others are a few mm high.
A wide spatula is used to fill the area between the ridges with putty compound.
(mixture of epoxy and micro-balloons)
After the first layer, a second layers is applied before the first layer is completely harden (to avoid sanding in between).
For this second layer I made the fairing compound a little thinner.

Yes, the Tornado hulls need to be covered .
Perhaps I will build some bulkheads or other parts in my heated workshop this winter.
