I like ultrakote over solid wood, but monokote beats it easily over open-bay structures. Colortex(worldtex, solartex - same thing) is the best fabric for adherence, shrink and staying down. For the best durable finish I like fibreglass and epoxy resin. I have not tried polyurethane resian with glass, but I intend to. Light finish, try the litfab from nelson's. Many new light covering material, so experiment.
Any one who says brand x is the best overall is probably inexperienced with the wide array of choices. I can put monokote over an open bay wing with no wrinkles without heating it to shrink all over. a little shrink and it is locked in forever (eight yaers on a P-51 w/o a sag. Ultra is harder to work with, it is stiff and wrinkles itself around curves. If you put it on with heat so it shrinks as you go, you can do compound curves beautifully.
Colortex is evan easier to use than a plastic 'kote'. It all depends on your desired effect. I have not used many neons, but in the 'kote' plastics, I have not found one that does not fad even in normal inside, light. Check a roll that has been in the shop for a while. The exposed first few inches will have faded on the rack.'
'Good luck. The finish is more dependent on your skill, not the material. Practice and do not expect perfection right away. Work toward your gaol, and have lots of patience while finishing.
